Patch Published: N/A
CVE [?]: CVE-2005-1415
CPE [?]: cpe:/a:globalscape:secure_ftp_server

Synopsis

The remote FTP server is affected by a buffer overflow vulnerability.

Description

The remote host is running GlobalSCAPE Secure FTP Server.

GlobalSCAPE Secure FTP Server 3.0.2 and prior versions are affected by a buffer overflow due to mishandling the user-supplied input.

An attacker would first need to authenticate to the server before they can execute arbitrary commands.

Solution

Upgrade to GlobalSCAPE Secure FTP 3.0.3 Build 4.29.2005 or later as this reportedly fixes the issue.
