추가 정보:

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

  • CVE-2018-4056

    An 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 disable 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.

안정 배포(stretch)에서, 이 문제를 버전 4.5.0.5-1+deb9u1에서 고쳤습니다.

coturn 패키지를 업그레이드 하는 게 좋습니다.
