CISA Adds Exploited Vulnerabilities to Catalog

CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: to view the newly added vulnerabilities in the catalog, click on the arrow on the of the "Date Added to Catalog" column, which will sort by descending dates.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known CVEs that carry significant risk to the federal enterprise. BOD 22-01 requires FCEB agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the Catalog that meet the meet the specified criteria.

CISA added a significant number of known exploited vulnerabilities to its catalog. CISA’s goal is to drive cybersecurity resources to fix the specific vulnerabilities that are actively exploited by nation-states and criminal groups in their attempts to compromise federal agencies, as well as U.S. critical infrastructure. These types of vulnerabilities are a frequent attack vector for malicious cyber actors of all types and pose significant risk to organizations of all sectors and sizes.

This latest addition of nearly 100 vulnerabilities is in part an outcome of our deep, trusted, and ongoing operational collaboration with our federal, industry, and Joint Cyber Defense Collaborative (JCDC) partners to identify and publish information about vulnerabilities that are being actively exploited by significant adversaries. Recognizing the significant number of vulnerabilities included in this update, CISA recommends that organizations prioritize mitigations of those vulnerabilities that are accessible via the Internet, affect mission-critical assets, or cannot be mitigated by compensating controls.

CISA is leaning forward, sharing these new vulnerabilities quickly so our partners in the federal government and across critical infrastructure can take action and remain vigilant. As America’s cyber defense agency, this is a key part of our mission to help our critical infrastructure partners reduce their risk to exploitation by threat actors. At this time, we are asking all organizations to have their ‘Shields Up’. The patching and mitigating of known exploited vulnerabilities is a key step to reducing the risk or impact of malicious cyber activity.

Your support to amplify this advisory through your communications and social media channels is appreciated. And as always, thank you for your continued collaboration.
