CVE-2025-20261
Cisco IMC SSH Privilege Escalation Vulnerability
Description
A vulnerability in the SSH connection handling of Cisco Integrated Management Controller (IMC) for Cisco UCS B-Series, UCS C-Series, UCS S-Series, and UCS X-Series Servers could allow an authenticated, remote attacker to access internal services with elevated privileges. This vulnerability is due to insufficient restrictions on access to internal services. An attacker with a valid user account could exploit this vulnerability by using crafted syntax when connecting to the Cisco IMC of an affected device through SSH. A successful exploit could allow the attacker to access internal services with elevated privileges, which may allow unauthorized modifications to the system, including the possibility of creating new administrator accounts on the affected device.
