CVE-2013-10065Public exploitNetwork attack vector

Unauthenticated SSH service crash via malformed key exchange

Published Aug 5, 2025 · Updated Nov 21, 2025

Denial of service in the SSH daemon of Sysax Multi Server 6.10 allows remote attackers to crash the service with a crafted key exchange. Its key-exchange parser processes 0x28 in a field that expects 0x1a, causing an uncaught exception instead of rejecting the malformed packet. No authentication or user interaction is required, and the consequence is limited to interruption of the SSH service.
