CVE-2019-0189 — The java.io.ObjectInputStream is known to cause Java serialisation issues
The java.io.ObjectInputStream is known to cause Java serialisation issues. This issue here is exposed by the "webtools/control/httpService" URL, and uses Java deserialization to perform code execution. In the HttpEngine, the value of the request parameter "serviceContext" is passed to the "deserialize" method of "XmlSerializer". Apache Ofbiz is affected via two different dependencies: "commons-beanutils" and an out-dated version of "commons-fileupload" Mitigation: Upgrade to 16.11.06 or manually apply the commits from OFBIZ-10770 and OFBIZ-10837 on branch 16

Unsafe deserialization and object reconstruction
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
- Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
- Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.
Remediate safely
- Replace native object deserialization with a data-only format and explicit schema validation.
- If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
- Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
