DescriptionCVE.org

improper handling of exceptional conditions, Allocation of resources without limits or throttling, Uncaught exception 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 Apache Thrift Java bindings before 0.25.0 allows remote, unauthenticated attackers to crash or exhaust resources on a service that deserializes attacker-controlled Thrift messages, because exceptional conditions on the message-handling path are not handled correctly and resource allocation is not bounded or throttled. Only deployments running affected Thrift Java server code on a network-reachable endpoint are at risk; impact is confined to availability (service crash / resource exhaustion) with no loss of confidentiality or integrity, and a specific precondition must hold - the crafted input must reach the vulnerable exception-handling or allocation path rather than any arbitrary request. …

Vulnerability AssessmentAI

Exploitation Requires a service built on the Apache Thrift Java bindings (version before 0.25.0) that exposes a network-reachable endpoint accepting and deserializing attacker-controlled Thrift messages. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a denial-of-service vulnerability (CWE-755, plus unbounded resource allocation and uncaught exceptions) in the Apache Thrift Java bindings before 0.25.0. … 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 Vendor-released patch: upgrade Apache Thrift Java bindings to 0.25.0, the version that fixes the improper exception handling and unbounded resource allocation; see the Apache advisory threads at https://lists.apache.org/thread/33otcgbqd27wf6qq810q56znzbomnhg1 and https://lists.apache.org/thread/5okpz47dv8hy0s3r6tmrplg3y7jzhhyw. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all deployments of Apache Thrift Java bindings, identify any server code on network-reachable endpoints, and treat versions before 0.25.0 as vulnerable; isolate those endpoints behind network controls or rate limiting if immediate patching is not possible. …
