CISA Adds Four Known Exploited Vulnerabilities to Catalog
CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2024-7399  Samsung MagicINFO 9 Server Path Traversal Vulnerability CVE-2024-57726  SimpleHelp Missing Authorization Vulnerability CVE-2024-57728  SimpleHelp Path Traversal Vulnerability CVE-2025-29635  D-Link DIR-823X Command Injection Vulnerability  These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.  Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities  established the KEV 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  KEV Catalog vulnerabilities  as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the  specified cr...
