  • Exploit targets the WebLogic T3 protocol interface; detect by monitoring for T3 handshake strings followed by large serialized object payloads containing 'aced0005' (Java serialization magic bytes) on port 7001.
  • Shodan/FOFA queries can identify exposed WebLogic instances: search for product:'oracle weblogic' or title='oracle peoplesoft sign-in' to find potentially vulnerable targets.
  • DNS-based out-of-band interaction (OAST) is used to confirm exploitation; monitor for unexpected DNS lookups originating from WebLogic server processes.
  • The exploit payload size prefix '00000460' (hex) in the T3 stream can serve as a network signature element for the MarshalledObject deserialization exploit.
  • ·The nuclei template targets two hosts per check: the generic hostname and hostname:7001 explicitly, meaning detection only fires if port 7001 is reachable or the default port resolves to T3.
  • ·Confirmation of exploitation relies on out-of-band DNS interaction (interactsh); environments blocking outbound DNS from the WebLogic server will not produce a match on the 'dns' word matcher.
