Title : Infoblox NIOS DNS Transaction ID Cache Poisoning Vulnerability
VUPEN ID : VUPEN/ADV-2008-2051
CVE ID : CVE-2008-1447
CWE ID : CWE-331
Rated as : Moderate Risk 
Remotely Exploitable : Yes

Release Date : 2008-07-10
|
A vulnerability has been identified in Infoblox NIOS, 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.
Affected Products
Infoblox NIOS versions 4.x
Solution
Upgrade to Infoblox NIOS version 4.2r5, 4.2r4-3 or 4.2r3-6.
