  • Detect exploit attempts by monitoring TCP connections to port 5555 carrying packets with the magic byte sequence \xFF\xFE\x32 (Unicode BOM + opcode marker) followed by crafted opcode fields (opcodes 11, 17, 20, 27, 28, 35, 42, 46) with oversized parameter strings (≥10000 bytes).
  • Alert on network traffic to TCP/5555 where the packet length field (first 4 bytes, big-endian) is followed by \xFF\xFE\x32\x00 and the payload length exceeds normal operational bounds (e.g., >5000 bytes), indicative of buffer overflow exploitation of omniinet.exe.
  • Monitor omniinet.exe for unexpected child process creation or shellcode execution; the exploit results in arbitrary code execution under SYSTEM context.
  • Detect the opcode 27 exploit packet by matching the fixed-length header \x27\xCA\xFF\xFE\x32 at offset 1 in the TCP stream on port 5555.
  • Detect the opcode 20 exploit by matching the Unicode-encoded string '20' (\x32\x00\x30\x00) in the opcode field position of packets sent to TCP/5555, combined with a long file path argument.
  • ·The ROP chain and return addresses in the exploits are hardcoded for specific DLL versions (MSVCR71.dll, omniinet.exe) on Windows 2003 R2 / XP SP3 / Server 2008; detection based on these addresses will not generalize across all OS/patch combinations.
  • ·The Metasploit module notes that if the 'Max' payload length gets too long (e.g., 10000 bytes), a busted heap can result, meaning very large packet sizes may cause a crash rather than code execution — detection rules should account for both crash-inducing and shell-spawning payload sizes.
  • ·HP's mitigation of enabling encrypted control communication services changes the wire format; detection signatures based on plaintext packet structure will not apply to encrypted sessions.
