Background
Typo3 is a popular content management system (CMS) written in PHP. It provides a flexible and extensible platform for building websites and web applications. The vulnerability affects Typo3 Core versions 4.5.0 - 4.5.5. Typo3 uses prepared statements for database queries, which are intended to prevent SQL injection attacks. However, due to a flaw in the implementation, if the parameter values are not properly replaced, it can lead to a SQL injection vulnerability. This vulnerability can only be exploited if two or more parameters are bound to the query and at least two of them come from user input.
Vulnerability Detail
The Typo3 SQL injection vulnerability arises from the faulty implementation of prepared statements. When user input is used as parameter values in a query, the system fails to properly sanitize and replace the input, allowing an attacker to inject malicious SQL code. This can lead to unauthorized access, data manipulation, or even complete compromise of the affected Typo3 installation. The severity of this vulnerability is rated as CRITICAL with a CVSS score of 9.8.
