F5 Networks BIG-IP : BIND vulnerability (K59448931)
High Nessus Plugin ID 105442
SynopsisThe remote device is missing a vendor-supplied security patch.
Description** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem.
When the candidate has been publicized, the details for this candidate will be provided. (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 Authoritative Transfer (AXFR) requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection with no other access control list (ACL) protection could be manipulated into :
providing an AXFR of a zone to an unauthorized recipient.
accepting bogus NOTIFY packets.
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.
