Description

Package : mosquitto Version : 0.15-2+deb7u1 CVE ID : CVE-2017-7650 Debian Bug :

CVE-2017-7650: Pattern based ACLs can be bypassed by clients that set their username/client id to ‘#’ or ‘+’. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.

The vulnerability only comes into effect where pattern based ACLs are in use, or potentially where third party plugins are in use.

For Debian 7 "Wheezy", these problems have been fixed in version 0.15-2+deb7u1.

We recommend that you upgrade your mosquitto packages.
