CVE-2012-10060
Sysax Multi Server versions prior to 5.55 contain a stack-based buffer overflow in its SSH service. When a remote attacker supplies an overly long username during authentication, the server copies the input to a fixed-size stack buffer without proper bounds checking. This allows remote code execution under the context of the service.
CVSS
