url /oo/backwards-compatibility/wsExecutionBridgeService↗

• → Monitor for HTTP POST requests to the endpoint /oo/backwards-compatibility/wsExecutionBridgeService, which is the attack vector for this Java deserialization RCE vulnerability. ↗
• → The vulnerability is exploitable via Java deserialization through endpoints using HttpInvokerServiceExporter (original) or the incomplete-fix SecureHttpInvokerServiceExporter; inspect deserialized payloads for non-RemoteInvocation root objects or malicious objects embedded in RemoteInvocation attributes map. ↗
• → An exploitable Apache Commons BeanUtils library is present on the classpath; detect gadget-chain payloads associated with Apache Commons BeanUtils in deserialized HTTP POST bodies to the affected endpoint. ↗
• → The bypass of LookAheadObjectInputStream works by embedding arbitrary serializable objects inside the RemoteInvocation attributes map; the firstTime flag only validates the first deserialized class, so subsequent nested objects are unchecked. ↗

• · The incomplete fix (SecureHttpInvokerServiceExporter / LookAheadObjectInputStream) only validates the first deserialized class via the firstTime boolean flag; all subsequent nested objects within the RemoteInvocation are deserialized without class verification, leaving the fix bypassable. ↗
• · The vulnerability affects HPE Operations Orchestration Community and Enterprise editions prior to v10.70; the partial fix was introduced in 10.60 but is insufficient. ↗
