How the Exploit Works

The vulnerability resides in a script named `/var/www/app/resetroot.php`, which lacks necessary authentication checks. When this script is executed, it performs a SQL update that sets the database administrator username to ‘root’ and its password to the SHA-512 hash of the string ‘password. This can allow an attacker to reset the MySQL root password and gain full control over the database.
Additionally, a deserialization issue exists in the commented-out code in `/var/www/app/lib/common/oses.php`, which unserializes session data. If this code is re-enabled or reached with attacker-controlled serialized data, it can lead to remote code execution.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request to trigger the `resetroot.php` script:

GET /resetroot.php HTTP/1.1
Host: target.example.com

After running this command, the MySQL root password would be reset, allowing the attacker to login with `username: root` and `password: password`.

Impact and Mitigation

The impact of this vulnerability is significant, as it could lead to complete system compromise and potential data leakage. Therefore, it is crucial to immediately apply the vendor patch once released. Until the patch is available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. Regular monitoring and logging of network activity can also assist in identifying any unusual or suspicious activities.
