| Vulnerability Description The Symantec Firewall has a DNS proxy service, DNSD.exe, that acts as a proxy and cache server for the DNS requests generated by internal systems. |
||
|
Vulnerability Details When the DNS proxy receives a DNS response from a DNS server, the information in the Authoritative and Additional Record will be saved in the DNS cache. There exists a vulnerability in the way the DNS proxy component of Symantec Gateway products processes and caches DNS responses. When the vulnerable component is configured to function as a DNS caching server or as a primary DNS server, it is susceptible to DNS cache poisoning under specific conditions. An attacker may exploit this vulnerability to do site spoofing, Man-in-the-Middle, or denial of service attacks by manipulating the DNS cache data on the target system. Upon receiving a specially crafted DNS response packet, the vulnerable Symantec Firewall DNS proxy service will cache invalid domain information in its cache without any verification, poisoning the cache. When a DNS request for the hijacked domain is made, information from the poisoned cache will be used to answer the request. Therefore, any client who utilizes this DNS Proxy service will be affected. This could be used to carry other types of attacks, such as man-in-the-middle attacks, or spoofing attacks, or information gathering attacks, etc. |
