A possible Cross-Site Scripting (XSS) vulnerability has been detected in the management console.
If there is a claim dialect configured with an XSS payload in the dialect URI, if a user picks up the malicious dialect URI and adds it as the service provider claim dialect while configuring the service provider, that payload gets executed. The attacker also needs to have privileges to log in to the management console, add and configure claim dialects.
By leveraging an XSS attack, an attacker can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise. However, since all the session related sensitive cookies are set with httpOnly flag and protected, session hijacking or similar attacks would not be possible.
