CVE-2025-20334 is a command injection vulnerability in the HTTP API subsystem of Cisco IOS XE Software. The flaw is caused by insufficient input validation of user-supplied data processed by API functionality exposed through the device’s HTTP management interface. An attacker can supply crafted input to vulnerable API requests and cause commands to be injected into the underlying operating system. Successful exploitation results in execution of arbitrary commands with root privileges. The issue affects Cisco IOS XE devices when the HTTP Server feature is enabled and can be reached either through direct authenticated administrative access or by abusing a logged-in administrator’s active session through a crafted link.
