Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A stack-based buffer overflow exists in Achat v0.150 in its default configuration. By sending a specially crafted message to the UDP port 9256, an attacker can overwrite the structured exception handler (SEH) due to insufficient bounds checking on user-supplied input leading to remote code execution.
