Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. 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

Dolibarr before 11.0.5 allows low-privilege users to upload files of dangerous types, leading to arbitrary code execution. This occurs because .pht and .phar files can be uploaded. Also, a .htaccess file can be uploaded to reconfigure access control (e.g., to let .noexe files be executed as PHP code to defeat the .noexe protection mechanism).
