A vulnerability in the web-based management interface of Cisco FXOS Software and 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 have valid credentials for a user account with the role of Administrator or AAA Administrator.
The severity of this vulnerability is classified as medium, with a CVSS score of 4.8. This indicates a moderate risk to organizations, particularly those utilizing Cisco FXOS and UCS Manager Software. The potential for exploitation, combined with the necessity for valid user credentials, presents a unique challenge for security teams.
Risk to organizations includes unauthorized access to sensitive user data and the ability to execute scripts that could compromise the security of the management interface. Given the critical nature of the management interfaces involved, organizations should prioritize patching immediately.
As of now, there are no known public exploits or proofs of concept available for this vulnerability. However, the attack vector remains a concern due to the implications of stored XSS attacks, which could lead to broader network compromises.
Organizations using the affected software should monitor their systems for suspicious activity and ensure that their user accounts have strong authentication measures in place.
