Vulnerability Assessment Details

proftpd mkdir buffer overflow

Vulnerability Assessment Summary
Checks if the remote ftp can be buffer overflown

Detailed Explanation for this Vulnerability Assessment

It was possible to make the remote FTP server crash
by creating a huge directory structure with
directory names not being longer than 255 chars.
This is usually called the 'proftpd buffer overflow'
even though it affects other FTP servers.

It is very likely that a possible hacker can use this
flaw to execute arbitrary code on the remote
server. This will give him a shell on your system,
which is not a good thing.

Solution : upgrade your FTP server.
Consider removing directories writable by 'anonymous'.
