Description
A vulnerability in the web-based management interface of Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the interface of an affected system. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious code into specific data fields in 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, an attacker must have valid administrative credentials.
Analysis
Stored XSS in Cisco Prime Infrastructure's web management interface allows authenticated administrators to inject malicious scripts that execute in other users' browsers, potentially leading to session hijacking or sensitive data theft. The vulnerability stems from insufficient input validation on specific data fields and requires valid admin credentials to exploit. …
