## Technical details

An authenticated remote code execution (RCE) vulnerability exists in Dolibarr ERP/CRM's expression evaluation engine, specifically within the dol_eval_standard() function in /htdocs/core/lib/functions.lib.php. The function implements two validation modes (blacklist and whitelist), but fails to apply critical forbidden string checks (such as SplFileObject) when operating in the default whitelist mode. Furthermore, the regex-based validation fails to account for PHP dynamic callable syntax and only explicitly blocks the ReflectionFunction class, allowing the instantiation of other dangerous classes. Attackers with administrator privileges can exploit this by creating 'computed extrafields' containing malicious PHP payloads, which are then executed via eval() when the field is rendered. The vulnerability is addressed in version 23.0.2 by improving string syntax checks and blocking PHP comments used for obfuscation.
