CVE-2026-20094

EUVD-2026-17948

01.04.2026, 17:28

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.

Common Weakness Enumeration

CWE-77 - Improper Neutralization of Special Elements used in a Command ('Command Injection')
The software constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
