Lifecycle Timeline
2Description
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks 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 code 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 administrative credentials.
Analysis
Cisco ISE and ISE-PIC's web management interface fails to properly sanitize user input, enabling authenticated admins to inject malicious scripts that execute in other users' browsers. Successful exploitation allows attackers with valid administrative credentials to steal session data or perform actions on behalf of legitimate users through reflected XSS attacks. …
