Title
Achat v0.150 SEH Buffer Overflow via UDP
Summary
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.
Severity ?
9.3 (Critical)
