• → Monitor for HTTP POST requests to the /oo/backwards-compatibility/wsExecutionBridgeService endpoint, which is the deserialization sink exploited by this CVE. ↗
• → The vulnerable endpoint uses HttpInvokerServiceExporter and ObjectInputStream.readObject(), making it susceptible to crafted serialized Java object payloads; inspect inbound traffic to this path for Java serialization magic bytes (0xACED0005). ↗
• → Exploitation chains include BeanUtils1, Spring1, and Spring2 gadget chains (not Apache Commons Collections); detection should not rely solely on Commons Collections gadget signatures. ↗
• → Post-exploitation artifact: look for pseudo-randomly named files created under C:\Users\Public that are short-lived (~30 seconds), as well as directories named beanutils_exploit, spring1_exploit, and spring2_exploit under the same path. ↗
• → The DiskFileItem class is involved in the exploit chain; monitor for its instantiation or serialization in Java deserialization traffic. ↗

• · The exploit does NOT use Apache Commons Collections gadget chains despite the CVE description referencing that library; detections based solely on Commons Collections gadget signatures will miss this exploit. ↗
