CVE-2024-0887Public exploitNetwork attack vector

Unauthenticated service interruption via repeated TCP connections

Published Jan 25, 2024 · Updated May 29, 2025

Denial of service in Mafiatic Blue Server 1.1 allows remote attackers to interrupt its HTTP service through repeated TCP connections. The public proof of concept repeatedly opens TCP connections to port 80 and sends a short non-HTTP string until new socket creation fails. No authentication or user interaction is required, but the disclosure does not establish whether the service crashes, hangs, or recovers when traffic stops.
