Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-20269 impacting cisco evolved_programmable_network_manager. Evaluated with CVSS Base Score of 6.5 (MEDIUM).

Original NVD Description

Source: NIST NVD
A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, low-privileged, remote attacker to retrieve arbitrary files from the underlying file system on an affected device. This vulnerability is due to insufficient input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface on an affected device. A successful exploit could allow the attacker to access sensitive files from the affected device.
