CVE-2025-20296: Cisco ucs manager cross-site scripting vulnerability

Cisco · Ucs Manager

A vulnerability in the web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious data into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must be a member of the Administrator or AAA Administrator role.
