What is CVE-2026-20096?
CVE-2026-20096 is a medium-severity command injection vulnerability in Cisco Unified Computing System, published on 1 Apr 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level 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. Cisco has assigned this vulnerability a Security Impact Rating (SIR) of High, rather than Medium as the score indicates, because additional security implications could occur once the attacker has become root.
Weakness: CWE-77
