## Technical details

A Remote Code Execution (RCE) vulnerability exists in the Website module of Dolibarr ERP/CRM versions up to and including 22.0.4. The application implements a blacklist-based filtering mechanism to block dangerous PHP functions (e.g., system, shell_exec, eval) within dynamic web content. However, this filter relies on simple string-based matching which can be bypassed using obfuscation techniques such as string concatenation, encoding, or indirect function invocation. An authenticated attacker with permissions to edit PHP content can leverage these bypasses to execute arbitrary operating system commands with the privileges of the web server. As of the advisory date, the vulnerability is addressed by avoiding blacklist-based security in favor of more robust input validation or disabling dynamic PHP execution.
