Description

The Soca web access control system suffers from multiple SQL Injection vulnerabilities. Input passed via multiple POST parameters is not properly sanitised before being returned to the user or used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and bypass the authentication mechanism. It allows the attacker to remotely disclose password hashes and login with MD5 hash with highest privileges resulting in unlocking doors and bypass the physical access control in place.
