The vulnerability is caused due to the banner-edit.php script allowing the upload of files with arbitrary extensions to a folder inside the webroot. This can be exploited to e.g. execute arbitrary PHP code by uploading a specially crafted PHP script that contains the GIF magic number.
This module exploits a Remote Code Execution vulnerability in Mantis version 1.1.3 caused by Mantis handling the sort parameter in manage_proj_page without the proper validation. This allows for remote code execution on Mantis' Web server. This module starts a web server on the Core Impact Console to publish the agent, which is downloaded from the target.
The BlogAPI module does not validate the extension of files that it is used to upload, enabling users with the "administer content with blog api" permission to upload harmful files. This module uploads an Core Impact agent, creates a php file to execute the agent and then makes a request to the file. The result is an Core Impact agent running on the webserver.
include/imageObjectIM.class.php in Coppermine Photo Gallery (CPG) before 1.4.15, when the ImageMagick picture processing method is configured, allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) quality, (2) angle, or (3) clipval parameter to picEditor.php.
