Debian Security Advisory
DLA-961-1 mosquitto -- LTS security update
- Date Reported:
- 30 May 2017
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2017-7650.
- More information:
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.
