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.

Zero-Day Flaw in Chrome and Chromium Puts Windows and Linux Users at Data Risk

 

A newly revealed zero-day vulnerability identified as CVE-2025-4664 has triggered serious concerns for billions of Google Chrome and Chromium users. Security experts have warned that this flaw, which affects both Windows and Linux platforms, could be exploited to leak sensitive cross-origin data such as OAuth tokens and session identifiers—all without requiring any user action.  

The vulnerability has been discovered within the Loader component of Chrome and Chromium browsers. It is linked to how these browsers interpret the Link HTTP header for sub-resource requests such as images or scripts. While most mainstream browsers follow strict guidelines for handling such requests, Chrome’s unique behavior stands out. It continues to respect the referrer-policy directive even when loading sub-resources, which can unintentionally expose sensitive information. 

This default behavior can be manipulated by attackers. A malicious site could inject a loose policy like “unsafe-url,” which then forces the browser to reveal complete URLs—including potentially sensitive credentials or session data—to third-party servers. This results in a severe breach of user privacy and circumvents traditional browser security measures. Cybersecurity firm Wazuh has stated that their Vulnerability Detection module can identify and address this specific flaw. 

The module leverages information from their Cyber Threat Intelligence (CTI) service to monitor browser versions and trigger alerts when vulnerable builds are detected. In controlled testing using Wazuh OVA 4.12.0, researchers were able to scan systems running Windows 11 and Debian 11 to determine if they were running affected versions of Chrome or Chromium. According to Wazuh’s platform, users can search for the vulnerability by querying CVE-2025-4664. If vulnerable software is found, the module changes the system status from “Active” to “Solved” after the necessary fixes are applied, helping administrators track progress in real time. 

In response to the discovery, Google has issued an emergency patch for Chrome users on Windows and Gentoo Linux. It is strongly recommended that users on these operating systems update their browsers immediately to avoid exposure. However, users on Debian 11 who rely on Chromium remain at risk, as no updated version has been released for that platform. All Chromium builds up to version 120.0.6099.224 are still considered vulnerable. Until a patch is available, security professionals advise uninstalling Chromium on affected Debian systems as a precautionary measure. 

While these immediate actions are important, experts caution that relying solely on browser updates is not a comprehensive defense. The broader cybersecurity strategy must include the use of endpoint protection platforms, anti-malware systems, and modern antivirus tools. These security layers can help detect and neutralize threats that slip past browser-based defenses and provide a stronger safety net for users and enterprises alike. 

As browser-based zero-day threats continue to emerge, users must remain vigilant. Rapid patching combined with proactive cybersecurity tools offers the best chance of mitigating risks and maintaining a secure browsing environment.

Windows CLFS Zero-Day CVE-2025-29824 Exploited by Ransomware Group Storm-2460

 

A newly disclosed Windows zero-day vulnerability, tracked as CVE-2025-29824, is being actively exploited in cyberattacks to deliver ransomware, Microsoft has warned. This flaw affects the Windows Common Log File System (CLFS) driver and enables local privilege escalation—a method often used by attackers after gaining initial access. 

Microsoft’s Threat Intelligence and Security Response teams revealed that the bug is classified as a “use-after-free” vulnerability with a severity score of 7.8. While attackers need to compromise a system before they can exploit this flaw, it remains highly valuable in ransomware operations. Cybercriminals often rely on these types of vulnerabilities to turn a limited foothold into full administrative control across networks. 

The cybercrime group currently leveraging this zero-day is known as Storm-2460. Microsoft reports that the group is using the exploit to deploy a custom backdoor named PipeMagic, which in turn facilitates the installation of RansomEXX ransomware—a variant not commonly observed but still capable of serious disruption. So far, Storm-2460 has targeted organizations in industries such as IT, finance, and retail, with victims located in countries including the United States, Spain, Saudi Arabia, and Venezuela. 

Microsoft emphasized that the number of known cases remains small, but the sophistication of the exploit is concerning. This attack is notable for being part of a “post-compromise” campaign, meaning the attacker already has a presence within the system before using the flaw. These types of exploits are frequently used to escalate privileges and move laterally within a network, eventually leading to broader ransomware deployment. Microsoft issued a security advisory for CVE-2025-29824 on April 8 and urged organizations to install updates immediately. Failure to do so could leave critical systems vulnerable to privilege escalation and full network compromise. 

To mitigate risk, Microsoft advises businesses to prioritize patch management, restrict unnecessary administrative privileges, and closely monitor for unusual behavior across endpoints. Cybersecurity teams are also encouraged to review logs for any indicators of compromise related to PipeMagic or RansomEXX. As ransomware tactics continue to evolve, the exploitation of vulnerabilities like CVE-2025-29824 reinforces the need for proactive defense strategies and rapid incident response protocols.

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.

CVE CVEs Cybersecurity Dark Web Data Breach Data Leak data security FortiGate devices Hackers

Hackers Leak 15,000 FortiGate Device Configs, IPs, and VPN Credentials

 

A newly identified hacking group, the Belsen Group, has leaked critical data from over 15,000 FortiGate devices on the dark web, making sensitive technical details freely available to cybercriminals. The leak includes configuration files, IP addresses, and VPN credentials, significantly increasing security risks for affected organizations. 

Emerging on cybercrime forums and social media just this month, the Belsen Group has been actively promoting itself. As part of its efforts, the group launched a Tor website where it released the stolen FortiGate data, seemingly as a way to establish its presence in the hacking community. In a post on an underground forum, the group claimed responsibility for breaching both government and private-sector systems, highlighting this operation as its first major attack. 

The exposed data is structured within a 1.6 GB archive, organized by country. Each country’s folder contains multiple subfolders corresponding to specific FortiGate device IP addresses. Inside, configuration files such as configuration.conf store FortiGate system settings, while vpn-passwords.txt holds various credentials, some of which remain in plaintext. 

Cybersecurity researcher Kevin Beaumont examined the leak and confirmed that these files include firewall rules, private keys, and other highly sensitive details that could be exploited by attackers. Further analysis suggests that the breach is linked to a known vulnerability from 2022—CVE-2022-40684—which was actively exploited before Fortinet released a security patch. 

According to Beaumont, evidence from a forensic investigation into a compromised device revealed that this zero-day vulnerability provided attackers with initial access. The stolen data appears to have been gathered in October 2022, around the same time this exploit was widely used. Fortinet had previously warned that CVE-2022-40684 was being leveraged by attackers to extract system configurations and create unauthorized super-admin accounts under the name fortigate-tech-support. 

Reports from the German news site Heise further confirm that the leaked data originates from devices running FortiOS firmware versions 7.0.0-7.0.6 or 7.2.0-7.2.2. The fact that FortiOS 7.2.2 was specifically released to address this vulnerability raises questions about whether some systems remained compromised even after the fix was made available. 

Although the leaked files were collected over two years ago, they still pose a significant threat. Configuration details, firewall rules, and login credentials could still be exploited if they were not updated after the original breach. Given the scale of the leak, cybersecurity experts strongly recommend that administrators review their FortiGate device settings, update passwords, and ensure that no outdated configurations remain in use.

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.
