====================================================================== 4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Pulse CMS, which can be exploited by malicious users to compromise a vulnerable system.

An error in the validation of uploaded image files can be exploited to upload files with an arbitrary extension to a folder within the web root. This can be exploited to upload and execute arbitrary PHP code.

Successful exploitation requires authentication.

====================================================================== 5) Solution

Partially fixed in version 1.2.4.

It can still be exploited to execute arbitrary PHP code by uploading a malicious PHP script with multiple extensions (e.g. "shell.php.gif") if Apache is not configured to handle the mime-type for media files with an e.g. "gif" extension.
