CISA Adds WatchGuard Firebox, Microsoft Windows, and Gladinet Triofox Vulnerabilities to KEV Catalog
CISA has updated its Known Exploited Vulnerabilities (KEV) Catalog to include three newly identified vulnerabilities: an out-of-bounds write in WatchGuard Firebox OS (CVE-2025-9242), a race condition in the Microsoft Windows kernel (CVE-2025-62215), and improper access control in Gladinet Triofox (CVE-2025-12480). These vulnerabilities have been added due to evidence of active exploitation, with risks ranging from remote code execution on network appliances to privilege escalation on Windows systems and unauthorized access to sensitive setup functions in Triofox. CISA emphasizes the critical nature of these flaws and urges immediate patching and mitigation to prevent exploitation.
Federal Civilian Executive Branch (FCEB) agencies are mandated under Binding Operational Directive (BOD) 22-01 to remediate these vulnerabilities by the specified deadlines, but CISA also strongly recommends that all organizations prioritize addressing these issues as part of their vulnerability management programs. The addition of these CVEs to the KEV Catalog highlights their significance as attack vectors and the ongoing threat they pose to both government and private sector networks. Organizations should verify their exposure and apply all relevant security updates without delay.
