CVE-2025-20269 — Cisco Evolved Programmable Network Manager security vulnerability

Medium CVSS 6.5

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.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
