Technical details

The vulnerability is an authentication bypass in the __construct method of /application/controllers/admin/Dashboard.php and other admin controllers in the CodeIgniter-based application. The root cause is missing or improperly implemented authentication validation in the constructor, allowing direct access to admin functions without session verification. The attack is network-accessible and requires no authentication or user interaction. An attacker can exploit this to gain unauthorized administrative access, execute arbitrary actions, and access or modify sensitive data. No patch information is currently available from the vendor.
