CRITICAL 9.3EPSS 3.02%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
