GNU Wget FTP Symlink Arbitrary Filesystem Access



This module exploits a vulnerability in Wget when used in recursive (-r) mode with a FTP server as a destination. A symlink is used to allow arbitrary writes to the target's filesystem. To specify content for the file, use the "file:/path" syntax for the TARGET_DATA option. Tested successfully with wget 1.14. Versions prior to 1.16 are presumed vulnerable.

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/server/wget_symlink_file_write
msf auxiliary(wget_symlink_file_write) > show actions
msf auxiliary(wget_symlink_file_write) > set ACTION < action-name >
msf auxiliary(wget_symlink_file_write) > show options
    ...show and set options...
msf auxiliary(wget_symlink_file_write) > 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.
