Description

Clement Berthaux from Synaktiv discovered two vulnerabilities in BIND, a DNS server implementation. They allow an attacker to bypass TSIG authentication by sending crafted DNS packets to a server.

  • CVE-2017-3142 An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection with no other ACL protection could be manipulated into :

    • providing an AXFR of a zone to an unauthorized recipient
    • accepting bogus NOTIFY packets
  • CVE-2017-3143 An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update.
