Overview

Dolibarr 23.0.4 < 24.0.1 Authorization Bypass

Dolibarr 23.0.4 before 24.0.1 contains an authorization bypass vulnerability that allows unauthenticated attackers to read arbitrary files through the document storage endpoints by supplying a crafted hashp parameter value.

Attackers can send a request with hashp=shared to skip token validation while satisfying the authorization condition in htdocs/document.php and htdocs/viewimage.php, gaining access to application logs, uploaded business documents, database backups containing password hashes, and files belonging to other multicompany entities.
