CVE-2026-20094

Cisco Unified Computing System

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. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.

Exploitation status

  • A vendor advisory or patch reference has been published.

What the metrics mean

  • It is reachable over a network, without needing local access.
  • For an attacker who can reach it, no special conditions are needed to exploit it.
  • To exploit it, an ordinary user account is needed.
  • Beyond that, no action by a user is required.
