Description:
otmorozok428 has reported a vulnerability in various WSN products, which can be exploited by malicious users to disclose sensitive information and compromise a vulnerable system.

Input passed to the "TID" parameter in index.php (when "custom" is set to "yes") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources. It can further be exploited to execute arbitrary PHP code by uploading a PHP script as an avatar and then including the script.

Successful exploitation requires valid user credentials.

The vulnerability is reported in WSN Links prior to 4.1.49, WSN Forum prior to 4.1.45, WSN Knowledge Base prior to 4.1.41, WSN Gallery prior to 4.1.40, and WSN Classifieds prior to 4.1.30.

Solution:
Update to WSN Links 4.1.49, WSN Forum 4.1.45, WSN Knowledge Base 4.1.41, WSN Gallery 4.1.40, and WSN Classifieds 4.1.30.
