Summary

Mailu before version 2024.06.52 has a missing authorization check in the REST API, allowing any unauthenticated attacker to remove IP restrictions or update the comment field of any existing user token if the REST API is enabled. Upgrade to version 2024.06.52 includes a patch, and a workaround is to disable the REST API.

Risk Assessment

An unauthenticated attacker can weaken token security, potentially leading to unauthorized access to user accounts and compromising the mail system.

Recommendation

Upgrade Mailu to version 2024.06.52 or later, or disable the REST API if not possible.

Original NVD description (English source)

Mailu is a mail server as a set of Docker images. Prior to version 2024.06.52, a missing authorization check in the Mailu admin REST API allows any unauthenticated attacker to remove any potential IP restriction or update the comment field from any existing user token provided the REST API is enabled. Upgrade to Mailu 2024.06.52 to receive a patch or, as a workaround, turn the REST API off.
