Description

Vulnerability Description

MyBulletinBoard (MyBB) contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'page' or 'usersearch' variables upon submission to the memberlist.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Solution Description

Currently, there are no known workarounds or upgrades to correct this issue. However, MyBB Group has released a patch to address this vulnerability.
