Description

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.
