Loading vulnerability…
Wireshark versions prior to 0.99.6 contain a vulnerability in the HTTP protocol dissector where a specially crafted HTTP response with chunked encoding, potentially involving a zero-length payload, can trigger a crash. This is due to improper handling of chunked encoding in the dissector code, leading to a denial of service condition when processing malicious network traffic.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/dos/wireshark/chunked.rb) that exploits a Denial of Service vulnerability in Wireshark 0.99.5 (CVE-2007-3389). The exploit works by sending a specially crafted HTTP response with chunked transfer encoding to a target being monitored by Wireshark. When Wireshark attempts to dissect this response, it crashes, resulting in a Denial of Service. The module allows the user to specify the source port and optionally spoof the source address. The payload is a raw TCP packet containing the malicious HTTP response, which includes headers referencing 127.0.0.1 and a sample file name. The exploit is a proof-of-concept and does not provide remote code execution, only service disruption. The code is written in Ruby and is designed to be run within the Metasploit framework.
