GoodTech SSH 6.4 lets logged‑in users run code

CVE-2008-4726 · published 18 years ago
Summary

The SFTP part of GoodTech SSH version 6.4 can be tricked by an authenticated user into running any program they choose if they send an overly long file name or command. This could allow a user who has already logged in to take full control of the server. Apply the vendor’s update or patch as soon as possible and restrict SFTP access to trusted users only.
