Vulnerability Note VU#620862

Golden FTP server contains a buffer overflow

Overview

Golden FTP server contains a buffer overflow that may allow a remote attacker to execute arbitrary code.

I. Description

Golden FTP server is a personal FTP server for the Microsoft Windows platform. The RNTO (rename to) command is used in conjunction with the RNFR (rename from) to rename a file on the server. Specifically, RNFR is used to specify the current name of the file, and RNTO is used to specify the new name for the file. If a remote unauthenticated attacker sends a specially crafted rename request (RNFR and RNTO) to a vulnerable Golden FTP server, they may be able to trigger a buffer overflow vulnerability in the routine that handles RNTO commands.

Please note that an exploit for this vulnerability is publicly available.

II. Impact

A remote unauthenticated attacker may be able to execute arbitrary code with the privileges of the Golden FTP server.

III. Solution

Upgrade

According to the developers of Golden FTP server, this issue has been corrected in Golden FTP server version 2.05b
