CVE-2024-39704Public exploitNetwork attack vector

Unauthenticated code execution via overwritten return address

Published Jun 28, 2024 · Updated Mar 20, 2025

Code execution in Soft Circle French-Bread Melty Blood: Actress Again: Current Code through 1.07 Rev. 1.4.0 allows remote attackers to execute code. A fixed-layout TCP/46318 packet places four attacker-controlled bytes in the saved return-address position, redirecting execution when the handler returns. No authentication or user interaction is required; successful exploitation runs arbitrary code in the affected game client's process.
