CVE-2026-20288

Medium

Description

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with Admin privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root.  This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs 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.  Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes root.
