Description

Dolibarr before 24.0.0 contains a broken object-level authorization vulnerability in the REST API third-party site account write routes that allows authenticated attackers with third-party creation rights to overwrite the WebPortal password of any company by bypassing per-object access checks that are only enforced on read routes. Attackers can replace the victim company's WebPortal password through the write endpoint, authenticate as that company to access its invoice data, and also obtain the victim's previous password verifier from the API response.
