CISA Urges Immediate Patching of Critical SysAid Vulnerabilities Amid Active Exploits

 

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert about two high-risk vulnerabilities in SysAid’s IT service management (ITSM) platform that are being actively exploited by attackers. These security flaws, identified as CVE-2025-2775 and CVE-2025-2776, can enable unauthorized actors to hijack administrator accounts without requiring credentials. 

Discovered in December 2024 by researchers at watchTowr Labs, the two vulnerabilities stem from XML External Entity (XXE) injection issues. SysAid addressed these weaknesses in March 2025 through version 24.4.60 of its On-Premises software. However, the urgency escalated when proof-of-concept code demonstrating how to exploit the flaws was published just a month later, highlighting how easily bad actors could access sensitive files on affected systems. 

Although CISA has not provided technical specifics about the ongoing attacks, it added the vulnerabilities to its Known Exploited Vulnerabilities Catalog. Under Binding Operational Directive 22-01, all Federal Civilian Executive Branch (FCEB) agencies are required to patch their systems by August 12. CISA also strongly recommends that organizations in the private sector act swiftly to apply the necessary updates, regardless of the directive’s federal scope. 

“These vulnerabilities are commonly exploited by malicious cyber actors and present serious threats to government systems,” CISA stated in its warning. SysAid’s On-Prem solution is deployed on an organization’s internal infrastructure, allowing IT departments to manage help desk tickets, assets, and other services. According to monitoring from Shadowserver, several dozen SysAid installations remain accessible online, particularly in North America and Europe, potentially increasing exposure to these attacks. 

Although CISA has not linked these specific flaws to ransomware campaigns, the SysAid platform was previously exploited in 2023 by the FIN11 cybercrime group, which used another vulnerability (CVE-2023-47246) to distribute Clop ransomware in zero-day attacks. Responding to the alert, SysAid reaffirmed its commitment to cybersecurity. “We’ve taken swift action to resolve these vulnerabilities through security patches and shared the relevant information with CISA,” a company spokesperson said. “We urge all customers to ensure their systems are fully up to date.” 

SysAid serves a global clientele of over 5,000 organizations and 10 million users across 140 countries. Its user base spans from startups to major enterprises, including recognized brands like Coca-Cola, IKEA, Honda, Xerox, Michelin, and Motorola.

Hackers Exploit End-of-Life SonicWall Devices Using Overstep Malware and Possible Zero-Day

 

Cybersecurity experts from Google’s Threat Intelligence Group (GTIG) have uncovered a series of attacks targeting outdated SonicWall Secure Mobile Access (SMA) devices, which are widely used to manage secure remote access in enterprise environments. 

These appliances, although no longer supported with updates, remain in operation at many organizations, making them attractive to cybercriminals. The hacking group behind these intrusions has been named UNC6148 by Google. Despite being end-of-life, the devices still sit on the edge of sensitive networks, and their continued use has led to increased risk exposure. 

GTIG is urging all organizations that rely on these SMA appliances to examine them for signs of compromise. They recommend that firms collect complete disk images for forensic analysis, as the attackers are believed to be using rootkit-level tools to hide their tracks, potentially tampering with system logs. Assistance from SonicWall may be necessary for acquiring these disk images from physical devices. There is currently limited clarity around the technical specifics of these breaches. 

The attackers are leveraging leaked administrator credentials to gain access, though it remains unknown how those credentials were originally obtained. It’s also unclear what software vulnerabilities are being exploited to establish deeper control. One major obstacle to understanding the attacks is a custom backdoor malware called Overstep, which is capable of selectively deleting system logs to obscure its presence and activity. 

Security researchers believe the attackers might be using a zero-day vulnerability, or possibly exploiting known flaws like CVE-2021-20038 (a memory corruption bug enabling remote code execution), CVE-2024-38475 (a path traversal issue in Apache that exposes sensitive database files), or CVE-2021-20035 and CVE-2021-20039 (authenticated RCE vulnerabilities previously seen in the wild). There’s also mention of CVE-2025-32819, which could allow credential reset attacks through file deletion. 

GTIG, along with Mandiant and SonicWall’s internal response team, has not confirmed exactly how the attackers managed to deploy a reverse shell—something that should not be technically possible under normal device configurations. This shell provides a web-based interface that facilitates the installation of Overstep and potentially gives attackers full control over the compromised appliance. 

The motivations behind these breaches are still unclear. Since Overstep deletes key logs, detecting an infection is particularly difficult. However, Google has shared indicators of compromise to help organizations determine if they have been affected. Security teams are strongly advised to investigate the presence of these indicators and consider retiring unsupported hardware from critical infrastructure as part of a proactive defense strategy.

Trend Micro Patches Critical Remote Code Execution and Authentication Bypass Flaws in Apex Central and PolicyServer

Trend Micro has rolled out essential security updates to address a series of high-impact vulnerabilities discovered in two of its enterprise security solutions: Apex Central and the Endpoint Encryption (TMEE) PolicyServer. These newly disclosed issues, which include critical remote code execution (RCE) and authentication bypass bugs, could allow attackers to compromise systems without needing login credentials. 

Although there have been no confirmed cases of exploitation so far, Trend Micro strongly recommends immediate patching to mitigate any potential threats. The vulnerabilities are especially concerning for organizations operating in sensitive sectors, where data privacy and regulatory compliance are paramount. 

The Endpoint Encryption PolicyServer is a key management solution used to centrally control full disk and media encryption across Windows-based systems. Following the recent update, four critical issues in this product were fixed. Among them is CVE-2025-49212, a remote code execution bug that stems from insecure deserialization within PolicyValue Table Serialization Binder class. This flaw enables threat actors to run code with SYSTEM-level privileges without any authentication. 

Another serious issue, CVE-2025-49213, was found in the PolicyServerWindowsService class, also involving unsafe deserialization. This vulnerability similarly allows arbitrary code execution without requiring user credentials. An additional bug, CVE-2025-49216, enables attackers to bypass authentication entirely due to faulty logic in the DbAppDomain service. Lastly, CVE-2025-49217 presents another RCE risk, though slightly more complex to exploit, allowing code execution via the ValidateToken method. 

While Trend Micro categorized all four as critical, third-party advisory firm ZDI classified CVE-2025-49217 as high-severity. Besides these, the latest PolicyServer release also fixes multiple other high-severity vulnerabilities, such as SQL injection and privilege escalation flaws. The update applies to version 6.0.0.4013 (Patch 1 Update 6), and all earlier versions are affected. Notably, there are no workarounds available, making the patch essential for risk mitigation. 

Trend Micro also addressed separate issues in Apex Central, the company’s centralized console for managing its security tools. Two pre-authentication RCE vulnerabilities—CVE-2025-49219 and CVE-2025-49220—were identified and patched. Both flaws are caused by insecure deserialization and could allow attackers to execute code remotely as NETWORK SERVICE without authentication. 

These Apex Central vulnerabilities were resolved in Patch B7007 for the 2019 on-premise version. Customers using Apex Central as a Service will receive fixes automatically on the backend. 

Given the severity of these cybersecurity vulnerabilities, organizations using these Trend Micro products should prioritize updating their systems to maintain security and operational integrity.

CVE CVE exploits CVEs Cyber Security Hacking WhatsApp Malwares Meta Meta Platforms MIME

WhatsApp Windows Vulnerability CVE-2025-30401 Could Let Hackers Deliver Malware via Fake Images

 

Meta has issued a high-priority warning about a critical vulnerability in the Windows version of WhatsApp, tracked as CVE-2025-30401, which could be exploited to deliver malware under the guise of image files. This flaw affects WhatsApp versions prior to 2.2450.6 and could expose users to phishing, ransomware, or remote code execution attacks. The issue lies in how WhatsApp handles file attachments on Windows. 

The platform displays files based on their MIME type but opens them according to the true file extension. This inconsistency creates a dangerous opportunity for hackers: they can disguise executable files as harmless-looking images like .jpeg files. When a user manually opens the file within WhatsApp, they could unknowingly launch a .exe file containing malicious code. Meta’s disclosure arrives just as new data from online bank Revolut reveals that WhatsApp was the source of one in five online scams in the UK during 2024, with scam attempts growing by 67% between June and December. 

Cybersecurity experts warn that WhatsApp’s broad reach and user familiarity make it a prime target for exploitation. Adam Pilton, senior cybersecurity consultant at CyberSmart, cautioned that this vulnerability is especially dangerous in group chats. “If a cybercriminal shares the malicious file in a trusted group or through a mutual contact, anyone in that group might unknowingly execute malware just by opening what looks like a regular image,” he explained. 

Martin Kraemer, a security awareness advocate at KnowBe4, highlighted the platform’s deep integration into daily routines—from casual chats to job applications. “WhatsApp’s widespread use means users have developed a level of trust and automation that attackers exploit. This vulnerability must not be underestimated,” Kraemer said. Until users update to the latest version, experts urge WhatsApp users to treat the app like email—avoid opening unexpected attachments, especially from unknown senders or new contacts. 

The good news is that Meta has already issued a fix, and updating the app resolves the vulnerability. Pilton emphasized the importance of patch management, noting, “Cybercriminals will always seek to exploit software flaws, and providers will keep issuing patches. Keeping your software updated is the simplest and most effective protection.” For now, users should update WhatsApp for Windows immediately to mitigate the risk posed by CVE-2025-30401 and remain cautious with all incoming files.

Cisco CVE-2024-20439: Exploitation Attempts Target Smart Licensing Utility Backdoor

 

A critical vulnerability tracked as CVE-2024-20439 has placed Cisco’s Smart Licensing Utility (CSLU) in the spotlight after cybersecurity researchers observed active exploitation attempts. The flaw, which involves an undocumented static administrative credential, could allow unauthenticated attackers to remotely access affected systems. While it’s still unclear whether the vulnerability has been weaponized in ransomware attacks, security experts have noted suspicious botnet activity linked to it since early January, with a significant surge in mid-March. 

The vulnerability, according to Cisco, cannot be exploited unless the CSLU is actively running—a saving grace for systems not using the utility frequently. However, many organizations rely on the CSLU to manage licenses for Cisco products without requiring constant connectivity to Cisco’s cloud-based Smart Software Manager. This increases the risk of exposure for unpatched systems. Johannes Ullrich, Dean of Research at the SANS Technology Institute, highlighted that the vulnerability effectively acts as a backdoor. 

In fact, he noted that Cisco has a history of embedding static credentials in several of its products. Ullrich’s observation aligns with earlier research by Nicholas Starke, who published a detailed technical analysis of the flaw, including the decoded hardcoded password, just weeks after Cisco issued its patch. This disclosure made it easier for potential attackers to identify and exploit vulnerable systems. In addition to CVE-2024-20439, Cisco addressed another critical flaw, CVE-2024-20440, which allows unauthenticated attackers to extract sensitive data from exposed devices, including API credentials. 

This vulnerability also affects the CSLU and can be exploited by sending specially crafted HTTP requests to a target system. Like the first flaw, it is only active when the CSLU application is running. Researchers have now detected attackers chaining both vulnerabilities to maximize impact. According to Ullrich, scans and probes originating from a small botnet are testing for exposure to these flaws. Although Cisco’s Product Security Incident Response Team (PSIRT) maintains that there’s no confirmed evidence of these flaws being exploited in the wild, the published credentials and recent scan activity suggest otherwise. 

These types of vulnerabilities raise larger concerns about the use of hardcoded credentials in critical infrastructure. Cisco has faced similar issues in the past with other software products, including IOS XE, DNA Center, and Emergency Responder. 

As always, the best defense is prompt patching. Cisco released security updates in September to address both flaws, and organizations running CSLU should immediately apply them. Additionally, any instance of the CSLU running unnecessarily should be disabled to reduce the attack surface. With exploit attempts on the rise and technical details now public, delaying mitigation could have serious consequences.

Hackers Exploit ThinkPHP and ownCloud Vulnerabilities from 2022 and 2023

 

Hackers are increasingly exploiting outdated security flaws in poorly maintained systems, with vulnerabilities from 2022 and 2023 seeing a surge in attacks. According to threat intelligence platform GreyNoise, malicious actors are actively targeting CVE-2022-47945 and CVE-2023-49103, affecting the ThinkPHP Framework and the open-source ownCloud file-sharing solution. 

Both vulnerabilities are critical, allowing attackers to execute arbitrary commands or steal sensitive data, such as admin credentials and license keys. CVE-2022-47945 is a local file inclusion (LFI) flaw in ThinkPHP versions before 6.0.14. If the language pack feature is enabled, unauthenticated attackers can remotely execute operating system commands. 

Akamai reported that Chinese threat groups have exploited this flaw since late 2023, and GreyNoise recently detected 572 unique IPs actively attacking vulnerable systems. Despite having a low Exploit Prediction Scoring System (EPSS) rating of just 7% and not being listed in CISA’s Known Exploited Vulnerabilities (KEV) catalog, CVE-2022-47945 remains under heavy assault. 

The second vulnerability, CVE-2023-49103, impacts ownCloud’s file-sharing software. It stems from a third-party library that leaks PHP environment details through a public URL. After its disclosure in November 2023, hackers began exploiting the flaw to steal sensitive data. A year later, it was named one of the FBI, CISA, and NSA’s top 15 most exploited vulnerabilities. 

Even though a patch was released over two years ago, many ownCloud systems remain unpatched and exposed. GreyNoise recently observed malicious activity from 484 unique IPs targeting this vulnerability. To defend against these active threats, users are strongly advised to upgrade to ThinkPHP 6.0.14 or later and ownCloud GraphAPI 0.3.1 or newer. 

Taking vulnerable systems offline or placing them behind a firewall can significantly reduce the attack surface and prevent exploitation. As hackers continue to leverage older, unpatched vulnerabilities, staying vigilant with timely updates and robust security practices remains crucial in protecting critical systems and sensitive data.

Critical Command Injection Vulnerability Found in Aviatrix Network Controller (CVE-2024-50603)

 


Jakub Korepta, Principal Security Consultant at Securing, has discovered a critical command injection vulnerability in the Aviatrix Network Controller, identified as CVE-2024-50603. This flaw, impacting versions 7.x through 7.2.4820, has been assigned the highest possible CVSS severity score of 10.0. It allows unauthenticated attackers to remotely execute arbitrary code, posing a severe threat to enterprises utilizing Aviatrix’s cloud networking solutions.

The root of this vulnerability lies in improper input handling within the Aviatrix Controller's API. While certain input parameters are sanitized using functions like escapeshellarg, others—most notably the cloud_type parameter in the list_flightpath_destination_instances action—remain unprotected. This oversight permits attackers to inject malicious commands into API requests, leading to remote code execution (RCE).

Jakub Korepta demonstrated this flaw by crafting a malicious HTTP request that redirected sensitive system files to an attacker-controlled server. By appending harmful commands to the vulnerable parameter, attackers can gain unauthorized access and execute arbitrary code on the targeted system.


In a proof-of-concept attack, Korepta successfully extracted the contents of the /etc/passwd file, highlighting the potential for data theft. However, the threat extends beyond data exfiltration. Exploiting this vulnerability could allow attackers to:
  • Execute Remote Code: Attackers can run commands with full system privileges, gaining complete control over the Aviatrix Controller.
  • Steal or Manipulate Data: Sensitive data stored on the system can be accessed, stolen, or altered.
  • Compromise Entire Networks: Successful exploitation could lead to lateral movement within enterprise networks, escalating the attack's impact.

Research uncovered 681 publicly exposed Aviatrix Controllers accessible via the Shodan search engine. These exposed systems significantly increase the risk, providing attackers with easily identifiable targets for exploitation.

Aviatrix has responded promptly by releasing version 7.2.4996, which addresses this vulnerability through enhanced input sanitization. This update effectively neutralizes the identified risk. All users are strongly urged to upgrade to this patched version immediately to secure their systems and prevent exploitation. Failure to apply this update leaves systems vulnerable to severe attacks.

Recommended actions for organizations include:
  • Immediate Patch Deployment: Upgrade to version 7.2.4996 or later to eliminate the vulnerability.
  • Network Access Controls: Restrict public access to Aviatrix Controllers and enforce strict network segmentation.
  • Continuous Monitoring: Implement robust monitoring systems to detect unauthorized activity or anomalies.

Lessons in Proactive Security

This incident underscores the critical need for proactive cybersecurity measures and routine software updates. Even advanced networking solutions can be compromised if proper input validation and security controls are neglected. Organizations must remain vigilant, ensuring that both internal systems and third-party solutions adhere to stringent security standards.

The discovery of CVE-2024-50603 serves as a stark reminder of how overlooked vulnerabilities can escalate into significant threats. Timely updates and consistent security practices are vital to protecting enterprise networks from evolving cyber risks.

Ransomware Gangs Actively Recruiting Pen Testers: Insights from Cato Networks' Q3 2024 Report

 

Cybercriminals are increasingly targeting penetration testers to join ransomware affiliate programs such as Apos, Lynx, and Rabbit Hole, according to Cato Network's Q3 2024 SASE Threat Report, published by its Cyber Threats Research Lab (CTRL).

The report highlights numerous Russian-language job advertisements uncovered through surveillance of discussions on the Russian Anonymous Marketplace (RAMP). Speaking at an event in Stuttgart, Germany, on November 12, Etay Maor, Chief Security Strategist at Cato Networks, explained:"Penetration testing is a term from the security side of things when we try to reach our own systems to see if there are any holes. Now, ransomware gangs are hiring people with the same level of expertise - not to secure systems, but to target systems."

He further noted, "There's a whole economy in the criminal underground just behind this area of ransomware."

The report details how ransomware operators aim to ensure the effectiveness of their attacks by recruiting skilled developers and testers. Maor emphasized the evolution of ransomware-as-a-service (RaaS), stating, "[Ransomware-as-a-service] is constantly evolving. I think they're going into much more details than before, especially in some of their recruitment."

Cato Networks' team discovered instances of ransomware tools being sold, such as locker source code priced at $45,000. Maor remarked:"The bar keeps going down in terms of how much it takes to be a criminal. In the past, cybercriminals may have needed to know how to program. Then in the early 2000s, you could buy viruses. Now you don't need to even buy them because [other cybercriminals] will do this for you."

AI's role in facilitating cybercrime was also noted as a factor lowering barriers to entry. The report flagged examples like a user under the name ‘eloncrypto’ offering a MAKOP ransomware builder, an offshoot of PHOBOS ransomware.

The report warns of the growing threat posed by Shadow AI—where organizations or employees use AI tools without proper governance. Of the AI applications monitored, Bodygram, Craiyon, Otter.ai, Writesonic, and Character.AI were among those flagged for security risks, primarily data privacy concerns.

Cato CTRL also identified critical gaps in Transport Layer Security (TLS) inspection. Only 45% of surveyed organizations utilized TLS inspection, and just 3% inspected all relevant sessions. This lapse allows attackers to leverage encrypted TLS traffic to evade detection.

In Q3 2024, Cato CTRL noted that 60% of CVE exploit attempts were blocked within TLS traffic. Prominent vulnerabilities targeted included Log4j, SolarWinds, and ConnectWise.

The report is based on the analysis of 1.46 trillion network flows across over 2,500 global customers between July and September 2024. It underscores the evolving tactics of ransomware gangs and the growing challenges organizations face in safeguarding their systems.
