CVE-2017-15693 — In Apache Geode before v1.4.0, the Geode server stores application objects in serialized form

High CVSS 7.5

In Apache Geode before v1.4.0, the Geode server stores application objects in serialized form. Certain cluster operations and API invocations cause these objects to be deserialized. A user with DATA:WRITE access to the cluster may be able to cause remote code execution if certain classes are present on the classpath.

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.
