TYPO3 Debug Mode Enabled

What is "TYPO3 Debug Mode Enabled?"

The "TYPO3 Debug Mode Enabled" module is designed to detect the presence of debug mode enabled in TYPO3, a popular content management system. Debug mode is a feature that provides detailed error messages and debugging information, which can be useful during development but should not be enabled in a production environment. This module focuses on identifying instances where debug mode is mistakenly left enabled, potentially exposing sensitive information and increasing the attack surface of the TYPO3 installation.

This module has a low severity level, indicating that while it may not pose an immediate threat, it is still important to address and disable debug mode to ensure the security and stability of the TYPO3 installation.

Impact

Enabling debug mode in TYPO3 can have several implications:

- Exposure of sensitive information: Debug mode may reveal internal system details, database credentials, or other sensitive information that could aid attackers in their exploitation attempts. - Potential security vulnerabilities: Debug mode can introduce security vulnerabilities if not properly configured or disabled, allowing attackers to gain unauthorized access or execute arbitrary code. - Performance degradation: Debug mode generates additional logging and diagnostic output, which can impact the performance and responsiveness of the TYPO3 application.

How the module works?

The "TYPO3 Debug Mode Enabled" module works by analyzing the HTTP response of the target TYPO3 installation and applying specific matching conditions. It checks for the presence of certain keywords in the response body, such as "TYPO3 Exception" or "Uncaught TYPO3 Exception." Additionally, it verifies if the HTTP status code is 500 (Internal Server Error).

If any of these conditions are met, the module flags the TYPO3 installation as having debug mode enabled. It does not perform any active exploitation or modification of the target system.

Example HTTP request template:

GET / HTTP/1.1
Host: example.com

The module matches the response against the following conditions:

- Response body contains either "TYPO3 Exception" or "Uncaught TYPO3 Exception" (case-sensitive). - HTTP status code is 500 (Internal Server Error).

If both conditions are satisfied, the module reports the presence of debug mode enabled in TYPO3.
