Description

This module exploits a vulnerability found in OpenEMR version 4.1.1 Patch 14 and lower.
When logging in as any non-admin user, it's possible to retrieve the admin SHA1 password
hash from the database through SQL injection. The SQL injection vulnerability exists
in the "new_comprehensive_save.php" page. This hash can be used to log in as the admin
user. After logging in, the "manage_site_files.php" page will be used to upload arbitrary
code.
