CVE-2026-20093
Estado: Pendiente de análisisCrítica (9.8)—
A vulnerability in the change password functionality of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to bypass authentication and gain access to the system as Admin.
This vulnerability is due to incorrect handling of password change requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to bypass authentication, alter the passwords of any user on the system, including an Admin user, and gain access to the system as that user.
