Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. 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

The DMS/ECM module in Dolibarr 11.0.4 allows users with the 'Setup documents directories' permission to rename uploaded files to have insecure file extensions. This bypasses the .noexe protection mechanism against XSS.
