STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2025-20125. PoCs published by İbrahimsql, Yuri08loveElaina.

AI-analyzed exploit summary This exploit leverages an authorization bypass vulnerability in Cisco ISE 3.0 to read sensitive configuration, force configuration reload, or reboot the system. It uses authenticated session tokens to send requests to specific API endpoints.

Description

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.
