A vulnerability in an API of Cisco ISE could allow an authenticated, remote attacker with valid read-only credentials to obtain sensitive information, change node configurations, and restart the node. This vulnerability is due to a lack of authorization in a specific API and improper validation of user-supplied data. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to attacker to obtain information, modify system configuration, and reload the device. Note: To successfully exploit this vulnerability, the attacker must have valid read-only administrative credentials. In a single-node deployment, new devices will not be able to authenticate during the reload time.

  • Monitor for HTTP GET requests to /api/v1/admin/config/export from read-only administrative accounts, which should not normally access this endpoint.
  • Detect the exploit tool's distinctive User-Agent string 'Mozilla/5.0 (compatible; ISE-Exploit)' in HTTP requests to Cisco ISE API endpoints.
  • Flag unexpected node reloads or configuration exports initiated via the REST API, particularly from read-only administrative sessions, as potential exploitation of CVE-2025-20125.
  • Correlate ISE API access using the ISESSIONID cookie from accounts that only hold read-only administrative roles against sensitive admin API paths.
  • ·Exploitation requires valid read-only administrative credentials; unauthenticated exploitation is not possible.
  • ·In a single-node ISE deployment, a successful reboot exploit will prevent new devices from authenticating during the reload window, causing an availability impact.
  • ·There are no workarounds available; the only mitigation is applying Cisco's software updates.
  • ·CVE-2025-20125 is tracked under Cisco Bug IDs CSCwk14901 and CSCwk14916 and is classified under CWE-285 (Improper Authorization) and CWE-502 (Deserialization of Untrusted Data).
