What to do now

  1. Check whether your systems use Oracle WebLogic Server version 12.2.1.4.0 or 14.1.1.0.0.
  2. If you’re on one of those versions, schedule an urgent upgrade/patch using Oracle’s July 2024 CPU remediation guidance (as referenced by Oracle security alerts).
  3. After applying the update, verify the WebLogic service is running the patched build and that the exposed ports/protocols are not reachable unless explicitly required.
  4. If you cannot patch immediately, implement the vendor-described mitigations promptly and restrict network reachability to reduce exposure.
  5. Confirm completion by reviewing access and error logs for suspicious connections over T3/IIOP-related network paths.
