SSH Tectia Server SFTP Filename Logging Format String

medium Nessus Plugin ID 20927

Language:

Synopsis

The remote SSH server may be affected by a format string vulnerability.

Description

The remote host is running SSH Tectia Server, a commercial SSH server.

According to its banner, the installed version of this software contains a format string vulnerability in its sftp subsystem. A remote, authenticated attacker may be able to execute arbitrary code on the affected host subject to his privileges or crash the server itself.

Solution

As a temporary solution, disable the sftp subsystem as described in the vendor advisory above. A better solution, though, is to upgrade to SSH Tectia Server version 4.3.7 or 4.4.2 or later.
