>> Cisco Products Remote DNS Cache Poisoning Vulnerability
Title : Cisco Products Remote DNS Cache Poisoning Vulnerability VUPEN ID : VUPEN/ADV-2008-2025 CVE ID : CVE-2008-1447 CWE ID : CWE-331
Rated as : Moderate Risk
Remotely Exploitable : Yes Locally Exploitable : Yes Release Date : 2008-07-09
Technical Description
A vulnerability has been identified in various Cisco products, which could be exploited by remote attackers to poison a vulnerable DNS cache. This issue is caused due to the DNS servers 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: DNS servers that are only authoritative, or servers where recursion is not allowed, are not affected.
