• Goodbye 3 / 5.2 Denial Of Service Toolkit

Since the early days of the Internet, 'denial-of-service' (DoS) attacks have been a fact of life. The goal of these attacks is to restrict on a grand scale the availability of certain online systems and/or services or to.

Goodbye 3 / 5.2 Denial Of Service Toolkit

1. # Exploit Title: Zookeeper Client Denial Of Service (Port 2181)
2. # Exploit Author: Brandon Dennis
3. # Software Link: http://zookeeper.apache.org/releases.html#download
4. # Tested on: Windows 2008 R2, Windows 2012 R2 x64 & x86
5. # Description: The wchp command to the ZK port 2181 will gather open internal files by each session/watcher and organize them for the requesting client.
6. # This command is CPU intensive and will cause a denial of service to the port as well as spike the CPU of the remote machine to 90-100% consistently before any other traffic.
7. # The average amount of threads uses was 10000 for testing. This should work on all 3.x+ versions of Zookeeper.
