CVE-2026-20094

Cisco IMC - Web-Based Management Interface

Cisco CVSS 8.8 Updated April 6, 2026

Executive Risk Summary

"A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with read-only privileges to perform command injection attacks on an affected system and execute arbitrary commands as the root user. This vulnerability is due to improper validation of user-supplied input, allowing an attacker to execute arbitrary commands on the underlying operating system as the root user."

Anticipated Attack Path

  1. 1. An attacker sends crafted commands to the web-based management interface of the affected software.
  2. 2. The improper validation of user-supplied input allows the attacker to inject malicious commands.
  3. 3. The attacker executes arbitrary commands on the underlying operating system as the root user, gaining full control of the system.

Am I Vulnerable?

  • Is the Cisco IMC web-based management interface exposed to the internet or accessible by untrusted users?
  • Are read-only privileges sufficient for an attacker to exploit this vulnerability in the current configuration?
  • Have all affected Cisco IMC systems been updated with the latest security patches?
