The Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert, adding a newly exploited vulnerability to its Known Exploited Vulnerabilities Catalog. The identified vulnerability, labeled CVE-2023-4762, specifically affects Google Chromium V8 and is recognized as a type confusion vulnerability. These types of vulnerabilities serve as frequent targets for malicious cyber actors and pose substantial risks to the federal enterprise. CISA emphasizes the significance of addressing vulnerabilities promptly to mitigate the threat landscape.
This addition to the Known Exploited Vulnerabilities Catalog aligns with Binding Operational Directive (BOD) 22-01, titled “Reducing the Significant Risk of Known Exploited Vulnerabilities.” The directive establishes the Catalog as a dynamic list of known Common Vulnerabilities and Exposures (CVEs) carrying significant risks to the federal enterprise. BOD 22-01 mandates Federal Civilian Executive Branch agencies to remediate identified vulnerabilities by specific due dates, aiming to fortify their networks against active threats. While the directive primarily applies to Federal Civilian Executive Branch agencies, CISA strongly encourages all organizations to prioritize the timely remediation of vulnerabilities listed in the Catalog to minimize exposure to cyberattacks.
CISA emphasizes its commitment to regularly updating the Known Exploited Vulnerabilities Catalog, ensuring that organizations stay informed about potential risks. As the threat landscape evolves, CISA continues to add vulnerabilities meeting specified criteria to the catalog, fostering a proactive and adaptive approach to cybersecurity.
