This module exploits a directory traversal vulnerability found in Bitweaver. When handling the 'overlay_type' parameter, view_overlay.php fails to do any path checking/filtering, which can be abused to read any file outside the virtual directory.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/scanner/http/bitweaver_overlay_type_traversal
msf auxiliary(bitweaver_overlay_type_traversal) > show actions
...actions...
msf auxiliary(bitweaver_overlay_type_traversal) > set ACTION < action-name >
msf auxiliary(bitweaver_overlay_type_traversal) > show options
...show and set options...
msf auxiliary(bitweaver_overlay_type_traversal) > run
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.
