Name of the Vulnerable Software and Affected Versions: Dolibarr version 13.0.2

Description: The website builder module in Dolibarr allows remote PHP code execution due to an incomplete protection mechanism. Specifically, while system, exec, and shell exec are blocked, backticks are not blocked, enabling this exploit.

Recommendations: For Dolibarr version 13.0.2, consider disabling the website builder module until a patch is available to prevent remote PHP code execution.
