What is CVE-2018-12550?

Eclipse Mosquitto versions 1.0 to 1.5.5 exhibit a misconfiguration vulnerability when using an empty ACL file. In such cases, Mosquitto defaults to allowing all access instead of enforcing security, creating a potential risk of unauthorized access. An empty ACL file, which should restrict access, leads to unrestricted access permissions, contrary to secure configurations.

Affected Version(s)

Eclipse Mosquitto 1.0

Eclipse Mosquitto <= 1.5.5
