CVE-2026-20097 - Vulnerability Details

Description

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level privileges to execute arbitrary code as the root user. This vulnerability is due to improper validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code 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.
