WebsiteBaker 2.8.3 page_id SQL Injection

A blind-based SQL injection vulnerability exists in the admin/pages/modify.php script used in WebsiteBaker 2.8.3. An attacker is able to inject SQL statements in the page_id variable due to a lack of input sanitization, resulting in the ability to run arbitrary SQL queries on the backend DB. Authentication is required to perform this attack.

Exploitation

Stages

1. The authenticated attacker sends a specially crafted request to “admin/pages/modify.php” with SQL injection in the “page_id” parameter.
2. The injected SQL statement is passed to the backend database with no output returned (blind-based injection).

Prerequisites

You will need a valid authenticated token for the target WebsiteBaker installation.
