>> F5 Networks Products DNS Protocol Cache Poisoning Vulnerability
Title : F5 Networks Products DNS Protocol Cache Poisoning Vulnerability VUPEN ID : VUPEN/ADV-2008-2113 CVE ID : CVE-2008-1447 CWE ID : CWE-331
Rated as : Moderate Risk
Remotely Exploitable : Yes Locally Exploitable : Yes Release Date : 2008-07-16
Technical Description
A vulnerability has been identified in various F5 Networks products, which could be exploited by remote attackers to poison a vulnerable DNS cache. This issue is caused due to the DNS server not sufficiently randomising DNS transaction IDs and UDP source ports in the DNS queries that they produce, which may allow an attacker to more easily forge DNS answers that can poison DNS caches.
Note: This vulnerability is only exploitable if recursion has been enabled in BIND. F5 Networks products reportedly do not enable recursion by default, with the exception of the BIG-IP LTM MSM module configured for local bind.
