Description

In ExtremeControl before 25.5.12, a cross-site scripting (XSS) vulnerability was discovered in a login interface of the affected application. The issue stems from improper handling of user-supplied input within HTML attributes, allowing an attacker to inject script code that may execute in a user's browser under specific interaction conditions. Successful exploitation could lead to exposure of user data or unauthorized actions within the browser context.
