CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog , based on evidence of active exploitation. CVE-2023-2 868  Barracuda Networks ESG Appliance Improper Input Validation Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note:  To view other newly added vulnerabilities in the catalog, click on the arrow in 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 Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (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 specified criteria .
