Detailsinfo

A vulnerability was found in Cisco Unified Computing System. It has been declared as critical. This vulnerability affects some unknown processing of the component Web-based Management Interface/CLI. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Multiple vulnerabilities in the CLI and web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker with administrative privileges to perform command injection attacks on an affected system and elevate privileges to root.   These vulnerabilities are due to insufficient input validation of command arguments supplied by the user. An attacker could exploit these vulnerabilities by authenticating to a device and submitting crafted input to the affected commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of the affected device with root-level privileges.

The advisory is available at sec.cloudapps.cisco.com. This vulnerability was named CVE-2025-20294 since 10/10/2024. The exploitation appears to be easy. The attack can be initiated remotely. The exploitation needs additional levels of successful authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/30/2025). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 258111 (Cisco UCS Fabric Interconnects Command Injection (cisco-sa-ucs-multi-cmdinj-E4Ukjyrz)), which helps to determine the existence of the flaw in a target environment.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (258111), EUVD (EUVD-2025-25943) and CERT Bund (WID-SEC-2025-1917). If you want to get best quality of vulnerability data, you may have to visit VulDB.
