TITLE:
WinFtp Server Log-SCR Feature Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA16461

VERIFY ADVISORY:
http://secunia.com/advisories/16461/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
WinFTP Server 1.x
http://secunia.com/product/4318/

DESCRIPTION:
Donato Ferrante has discovered a vulnerability in WinFtp Server,
which potentially can be exploited by malicious people to compromise
a vulnerable system.

The vulnerability is caused due to a boundary error in the "Log-SCR"
feature when logging requests to screen. This can be exploited to
cause a buffer overflow via an overly long request.

Successful exploitation may allow execution of arbitrary code, but
requires that "Log-SCR" is enabled and may also require that the
application runs on certain versions of Windows. It also requires
that the administrator scrolls down the log screen to view the
malicious entry.

The vulnerability has been confirmed in version 1.6.8. Other versions
may also be affected.

SOLUTION:
Disable the "Log-SCR" feature.

PROVIDED AND/OR DISCOVERED BY:
Donato Ferrante
