Debian DLA-1671-1 : coturn security update

critical Nessus Plugin ID 122098

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities were discovered in coTURN, a TURN and STUN server for VoIP.

CVE-2018-4056

A SQL injection vulnerability was discovered in the coTURN administrator web portal. As the administration web interface is shared with the production, it is unfortunately not possible to easily filter outside access and this security update completely disables the web interface. Users should use the local, command line interface instead.

CVE-2018-4058

Default configuration enables unsafe loopback forwarding. A remote attacker with access to the TURN interface can use this vulnerability to gain access to services that should be local only.

CVE-2018-4059

Default configuration uses an empty password for the local command line administration interface. An attacker with access to the local console (either a local attacker or a remote attacker taking advantage of CVE-2018-4058) could escalade privileges to administrator of the coTURN server.

For Debian 8 'Jessie', these problems have been fixed in version 4.2.1.2-1+deb8u1.

We recommend that you upgrade your coturn packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected coturn package.
