The remote SSH server is affected by a format string vulnerability.
The remote SSH server is affected by a format string vulnerability. The remote host is running AttachmateWRQ Reflection for Secure IT Server / F-Secure SSH Server, a commercial SSH server. According to its banner, the installed version of this software contains a format string vulnerability in its SFTP subsystem. An remote authenticated attacker may be able to execute arbitrary code on the affected host subject to his privileges or crash the server itself.
Upgrade or patch according to vendor recommendations or edit the software's configuration to disable the SFTP subsystem.
