This vulnerability exists in the web-based management interface of several Cisco products including Cisco Finesse, Packaged Contact Center Enterprise, Unified Contact Center Enterprise, Unified Contact Center Express, and Unified Intelligence Center.
It allows an unauthenticated, remote attacker to perform cross-site scripting (XSS) attacks by injecting malicious code into specific pages of the interface. This happens because the interface does not properly validate user-supplied input.
If successfully exploited, the attacker can execute arbitrary script code within the context of the affected interface or access sensitive information stored in the browser.
How can this vulnerability impact me? :
The vulnerability can impact you by allowing an attacker to execute arbitrary scripts in your web management interface without authentication.
This could lead to unauthorized access to sensitive browser-based information or manipulation of the interface, potentially compromising the security and integrity of the affected system.
