CVE-2026-20094

High

Description

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.
