Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Dolibarr/dolibarr, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In Dolibarr ERP & CRM <= 22.0.4, PHP code detection and editing permission enforcement in the Website module is not applied consistently to all input parameters, allowing an authenticated user restricted to HTML/JavaScript editing to inject PHP code through unprotected inputs during website page creation. A patch is available at https://github.com/Dolibarr/dolibarr/releases/tag/23.0.0.
