Technical ContextAI · show details

This vulnerability is classified as Unrestricted File Upload (CWE-434), which allows attackers to upload malicious files that can be executed on the server. 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). Affected products include: Dolibarr. Version information: before 11.0.5.

Attack Technique

Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
