Technical details
CVE-2026-76424 is a path traversal / arbitrary file upload vulnerability in the Cisco ISE REST API caused by insufficient validation of file operation parameters. An authenticated attacker with valid administrative credentials can upload a file with a crafted path to bypass directory restrictions and place malicious files at arbitrary locations on the affected device. A successful exploit allows execution of arbitrary commands with root privileges. The vulnerability requires network access to the REST API port and valid administrative credentials; no user interaction is needed. Cisco has released software updates to address this issue, with no known workarounds available.
