Description:
V4mu has discovered a vulnerability in UBB.threads, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "thispath" parameter in addpost_newpoll.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.
Example:
http://[host]/addpost_newpoll.php?addpoll=preview&thispath=[file]
Successful exploitation requires that "register_globals" is enabled.
The vulnerability has been confirmed in version 6.5.1.1 (trial) and has also been reported in versions 6.4 through 6.5.2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified.
Set "register_globals" to "Off".
