F5 Networks BIG-IP : BIND vulnerability (K59448931)

Medium Nessus Plugin ID 105442

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

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 or accepting bogus NOTIFY packets. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1, 9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2. (CVE-2017-3142)

Impact

BIG-IP

An attacker may be permitted to view the entire contents of a zone when the vulnerability is exploited. For the BIG-IP system to be considered vulnerable, it must have the allow-transfer statement with TSIG authentication configured in BIND. This configuration combination is not a default configuration.

F5 iWorkflow, BIG-IQ, and Enterprise Manager

There is no impact. Although the BIG-IQ and Enterprise Manager software contain the vulnerable code, the BIG-IQ and Enterprise Manager systems do not use the vulnerable code in a way that exposes the vulnerability in default, standard, or recommended configurations.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K59448931.
