DescriptionCVE.org

Allocation of Resources Without Limits or Throttling vulnerability in Apache Thrift Java bindings.

This issue affects Apache Thrift: before 0.25.0.

Users are recommended to upgrade to version 0.25.0, which fixes the issue.

AnalysisAI

Denial of service in the Java bindings of Apache Thrift (all versions before 0.25.0) allows an accepted protocol peer to exhaust server resources by triggering unbounded allocation while Thrift messages are received and parsed. Per the assessed CVSS vector (PR:L), the attacker must already be an authenticated or otherwise accepted client of the Thrift service rather than an anonymous internet actor, which materially narrows exposure for deployments that only accept connections from trusted peers. …

Vulnerability AssessmentAI

Exploitation Requires a running service that uses Apache Thrift's Java bindings (versions before 0.25.0) to receive and parse Thrift protocol messages from a client. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a moderate-severity denial-of-service issue (CVSS 4.0 base 7.1) in Apache Thrift's Java bindings, stemming from unbounded resource allocation (CWE-770). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Apache Thrift to 0.25.0 or later, which the vendor states fixes this issue; apply the upgrade to every Java service, library dependency, and shaded/fat JAR that bundles the Thrift Java runtime, and rebuild dependent applications so the patched classes are actually on the classpath. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, confirm whether Apache Thrift Java bindings are in use anywhere in the estate, inventory the affected versions (anything below 0.25.0), and identify which services accept Thrift connections and from whom; where feasible, tighten network access so only strictly necessary trusted peers can connect, and add monitoring/alerting on memory and CPU spikes or connection anomalies in Thrift-serving processes. …
