According to its version number, the remote WS_FTP server is vulnerable to 
multiple flaws.

- A buffer overflow, caused by a vulnerability in the ALLO handler, an
attacker can then execute arbitrary code

- A flaw which allow an attacker to gain elevated privileges (SYSTEM level privileges)

- A local or remote attacker, with write privileges on a directory can create a
specially crafted file containing a large REST argument and resulting to a denial
of service

** OpenVAS only checked the version number in the server banner.

Solution : Upgrade to the latest version of this software.
Risk factor : High";
