Description:
Aria-Security Team have discovered a vulnerability in MercuryBoard, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "message" parameter in index.php when previewing PMs in the messenger is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that the target user has valid user credentials.
The vulnerability is confirmed in version 1.1.5. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
