TITLE:
Gene6 FTP Server Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA14436

VERIFY ADVISORY:
http://secunia.com/advisories/14436/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Gene6 FTP Server 3.x
http://secunia.com/product/4756/

DESCRIPTION:
Sowhat has reported a vulnerability in Gene6, which can be exploited
by malicious, local users to gain escalated privileges.

The vulnerability is caused due to a design error where unprivileged
users can modify settings of the FTP Server. This can e.g. be
exploited by adding a new "SITE" command mapped to an arbitrary
executable file.

Successful exploitation allows execution of arbitrary code with
escalated privileges.

SOLUTION:
The vendor recommends creating an administrator account and
unchecking "Allow all access" options to localhost in the
administration properties when running in a multi-user environment.

PROVIDED AND/OR DISCOVERED BY:
