CISA Updates its Database With 10 New Actively Exploited Vulnerabilities

Private firms should analyze the Catalog and fix any infrastructure weaknesses.

 

A high-severity security vulnerability impacting industrial automation software from Delta Electronics was among 10 new actively exploited vulnerabilities that the U.S. Cybersecurity and Infrastructure Security Agency (CISA) listed in its Known Exploited Vulnerabilities (KEV) Database on Friday.

FCEB agencies are required to address the vulnerabilities by the deadline in accordance with Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, in order to safeguard their networks from attacks that take advantage of the flaws in the catalog.

Private firms should analyze the Catalog and fix any infrastructure weaknesses, according to experts.

The problem, which has a CVSS score of 7.8, affects DOPSoft 2 versions 2.00.07 and earlier. It is listed as CVE-2021-38406. A successful exploit of the issue could result in the execution of arbitrary code.

Delta Electronics DOPSoft 2's incorrect input validation causes an out-of-bounds write that permits code execution, according to a CISA notice. "Delta Electronics DOPSoft 2 lacks sufficient validation of user-supplied data when parsing specified project files," the alert stated.

Notably, CVE-2021-38406 was first made public as part of an industrial control systems (ICS) advisory that was released in September 2021.

It is crucial to emphasize that the impacted product is no longer being produced and that there are no security updates available to solve the problem. On September 15, 2022, Federal Civilian Executive Branch (FCEB) organizations must abide by the directive.

The nature of the attacks that take advantage of the security issue is not well known, but a recent analysis by Palo Alto Networks Unit 42 identified instances of in-the-wild assaults that took place between February and April 2022.

The development supports the idea that attackers are becoming more adept at using newly reported vulnerabilities as soon as they are made public, which encourages indiscriminate and opportunistic scanning attempts that intend to benefit from postponed patching.

Web shells, crypto miners, botnets, remote access trojans (RATs), initial access brokers (IABs), and ransomware are frequently used in a precise order for the exploitation of these assaults.

CVE-2021-31010 (CVSS score: 7.5), an unpatched hole in Apple's Core Telephony component that could be used to get around sandbox constraints, is another high-severity flaw added to the KEV Catalog. In September 2021, the tech giant corrected the flaw.

The IT giant appears to have quietly updated its advisory on May 25, 2022, to add the vulnerability and clarify that it had actually been utilized in attacks, even though there were no signs that the hole was being exploited at the time.

The iPhone manufacturer said that it was aware of a claim that this flaw might have been extensively exploited at the time of release. Citizen Lab and Google Project Zero were credited with making the finding. 

Another noteworthy aspect of the September update is the patching of CVE-2021-30858 and CVE-2021-30860, both of which were used by NSO Group, the company behind the Pegasus spyware, to circumvent the security measures of the operating systems.

This suggests that CVE-2021-31010 may have been linked to the previously described two issues as part of an attack chain to get past the sandbox and execute arbitrary code.
