CVE-2016-0360 — Ibm Websphere Mq Jms security vulnerability

Critical CVSS 9.8

IBM Websphere MQ JMS 7.0.1, 7.1, 7.5, 8.0, and 9.0 client provides classes that deserialize objects from untrusted sources which could allow a malicious user to execute arbitrary Java code by adding vulnerable classes to the classpath. IBM Reference #: 1983457.

Matched remediation archetype

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.
