Cisco Releases Patches for 48 Firewall Vulnerabilities
🔒 Cisco has published 25 joint advisories addressing 48 vulnerabilities across its Secure Firewall ASA, Secure FMC and FTD product lines. The two most critical flaws, CVE-2026-20079 and CVE-2026-20131, are rated CVSS 10 and impact Secure FMC, enabling authentication bypass and remote code execution respectively. The auth bypass can be triggered with crafted HTTP requests against a boot-created system process, while the RCE stems from insecure deserialization of a user-supplied Java byte stream to the web management interface. There are no workarounds; Cisco urges customers to install the fixed software and the bundle also addresses 15 high and 31 medium severity issues.
