TWiki MAKETEXT Remote Command Execution

Description

This module exploits a vulnerability in the MAKETEXT Twiki variable. By using a specially crafted MAKETEXT, a malicious user can execute shell commands since user input is passed to the Perl "eval" command without first being sanitized. The problem is caused by an underlying security issue in the CPAN:Locale::Maketext module. This works in TWiki sites that have user interface localization enabled (UserInterfaceInternationalisation variable set). If USERNAME and PASSWORD aren't provided, anonymous access will be tried. Also, if the 'TwikiPage' option isn't provided, the module will try to create a random page on the SandBox space. The module has been tested successfully on TWiki 5.1.2 as distributed with the official TWiki-VM-5.1.2-1 virtual machine.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/unix/webapp/twiki_maketext
msf exploit(twiki_maketext) > show targets
    ...targets...
msf exploit(twiki_maketext) > set TARGET < target-id >
msf exploit(twiki_maketext) > show options
    ...show and set options...
msf exploit(twiki_maketext) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
