What's Happening?
Cisco Systems has released patches for a critical vulnerability in its Secure Firewall Management Center (FMC) platform, which is used for managing and monitoring Cisco's security solutions. The vulnerability, identified as CVE-2025-20265, affects instances with Radius authentication enabled and can be exploited by remote, unauthenticated attackers for arbitrary code execution. Cisco explained that the flaw is due to improper handling of user input during the authentication phase, allowing attackers to execute commands at a high privilege level. In addition to this critical flaw, Cisco addressed over a dozen high-severity vulnerabilities in its FMC, Secure Firewall Threat Defense (FTD), and Secure Firewall Adaptive Security Appliance (ASA) products. These vulnerabilities could be exploited for remote denial-of-service (DoS) attacks, among other threats. Cisco has provided patches and a software checker tool to help customers identify impacted products and apply necessary fixes.
