CVE-2023-3234Public exploitNetwork attack vector

Authenticated data disclosure via put_image deserialization

Published Jun 14, 2023 · Updated Aug 2, 2024

Deserialization in CRMEB 4.0 through 4.6.0 allows remote authenticated users to disclose data through the put_image endpoint. The disclosure identifies put_image in api/controller/v1/PublicController.php but does not publish the attacker-controlled input or deserialization call. Low-privileged access is required, and the documented consequence is limited to confidentiality loss.
