Executive Summary

This vulnerability allows an attacker who can publish to a queue consumed by an application to crash the consumer JVM by sending a single compressed message around 1 MB in size. The issue stems from unbounded decompression of attacker-supplied compressed message bodies.

Detection Guidance

Monitor for application crashes or JVM terminations after receiving messages. Check logs for OutOfMemoryError or System.exit(99) events. Inspect message queues for unusually large messages (~1 MB) with compressed payloads.

Impact Analysis

An attacker could exploit this to cause a denial of service by crashing the application repeatedly. The default error handler terminates the JVM with System.exit(99) on OutOfMemoryError, and redelivery on restart can lead to continuous crashes until manually purged.

Compliance Impact

This vulnerability could indirectly impact compliance with GDPR or HIPAA by causing service disruptions due to application crashes. A crash-loop scenario may lead to prolonged downtime, potentially affecting data processing or availability requirements under these regulations.

Mitigation Strategies

Upgrade to fixed versions of Spring AMQP: 4.1.1 OSS, 4.0.5 OSS, 3.2.13, or 2.4.19 (Enterprise Support Only). No additional mitigation steps are required beyond upgrading.
