Vulnerability Title
Reflected Cross-Site Scripting via URL Parameter in Multiple WSO2 Products Enables UI Redirection and Modification
Source: CVE Program / CVE List V5
Vulnerability Description
The affected product accepts user-supplied input within a URL parameter without enforcing expected sanitization or encoding before rendering it within the response. This condition allows for the injection of malicious JavaScript payloads. An attacker can leverage this vulnerability to cause the user's browser to redirect to a malicious website, modify the user interface of the webpage, or retrieve sensitive information from the browser. However, the impact is mitigated for session hijacking as all session-related sensitive cookies are protected by the httpOnly flag.
