DescriptionCVE.org

Uncontrolled Recursion vulnerability in Apache Thrift Dart and Java ME 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

Uncontrolled recursion in the Dart and Java ME bindings of Apache Thrift before 0.25.0 lets a remote, unauthenticated attacker crash or hang a service by sending a Thrift message containing deeply nested or self-referential structures that exhaust the parser's stack. Impact is availability-only (no confidentiality or integrity effect per the assessed CVSS:3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), and the vulnerable surface is confined to deployments that deserialize untrusted data using the Dart or Java ME bindings, so most Thrift users on Java SE, C++, Python, or Go are not exposed. …

Vulnerability AssessmentAI

Exploitation Exploitable only where an application deserializes attacker-controlled Thrift data using the Apache Thrift Dart binding or the Java ME binding at a version before 0.25.0; other language bindings are not affected. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a denial-of-service vulnerability (CWE-674, Uncontrolled Recursion) whose real-world priority is moderate rather than critical despite the 8.7 CVSS 4.0 base score. … 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 to version 0.25.0, which fixes the uncontrolled-recursion condition in the Dart and Java ME bindings as stated in the Apache advisories (https://lists.apache.org/thread/33otcgbqd27wf6qq810q56znzbomnhg1 and https://lists.apache.org/thread/oqr0h2k1cg9hho3oh8trmovmxc04fl5m). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify every Apache Thrift deployment and determine which ones use the Dart or Java ME bindings and accept Thrift messages from untrusted sources; for any such service, immediately cap inbound message size and structure-nesting depth at the API gateway, WAF, or load balancer, apply rate limiting, and enforce process resource limits (reduced stack size, memory caps, and automatic restart on crash) so a stack-exhaustion attempt cannot take the service down for long. …
