Exploitation Summary

EIP tracks 1 public exploit for CVE-2004-0789. PoCs published by HimmeL-Byte.

AI-analyzed exploit summary The repository contains a functional Python script that exploits CVE-2004-0789, a DNS vulnerability, by sending a large number of crafted DNS queries to a target server, potentially causing a denial-of-service (DoS) condition. The script uses Scapy to generate random DNS queries with varying domain names.

Description

Multiple implementations of the DNS protocol, including (1) Poslib 1.0.2-1 and earlier as used by Posadis, (2) Axis Network products before firmware 3.13, and (3) Men & Mice Suite 2.2x before 2.2.3 and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (CPU and network bandwidth consumption) by triggering a communications loop via (a) DNS query packets with localhost as a spoofed source address, or (b) a response packet that triggers a response packet.
