Titan FTP XCRC Directory Traversal Information Disclosure



This module exploits a directory traversal vulnerability in the XCRC command implemented in versions of Titan FTP up to and including 8.10.1125. By making sending multiple XCRC command, it is possible to disclose the contents of any file on the drive with a simple CRC "brute force" attack. Although the daemon runs with SYSTEM privileges, access is limited to files that reside on the same drive as the FTP server's root directory.

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 auxiliary/scanner/ftp/titanftp_xcrc_traversal
msf auxiliary(titanftp_xcrc_traversal) > show actions
msf auxiliary(titanftp_xcrc_traversal) > set ACTION < action-name >
msf auxiliary(titanftp_xcrc_traversal) > show options
    ...show and set options...
msf auxiliary(titanftp_xcrc_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.
