Description PRE-NVD

Disclosed via oss-security. NVD scoring and full description are pending.

AnalysisAI

Out-of-bounds read in Apache Thrift C++ JSON deserialization allows remote attackers to leak sensitive information and trigger denial of service via malformed JSON payloads. Affects Apache Thrift versions prior to 0.23.0. The vulnerability has low exploitation probability (EPSS 0.02%) and is not currently listed in CISA KEV, suggesting limited real-world weaponization despite network-accessible attack vector.

Technical ContextAI

Apache Thrift is a cross-language RPC framework that includes language-specific implementations for serialization and deserialization. The vulnerability exists in the C++ JSON protocol handler, specifically in the skip() function which recursively processes JSON structures without proper bounds validation. The out-of-bounds read (CWE-125) occurs when processing malformed or deeply nested JSON, allowing an attacker to read memory beyond allocated buffer boundaries. This impacts any Thrift service using the C++ JSON protocol for message handling, though exploitation requires the service to process untrusted JSON input.

RemediationAI

Upgrade Apache Thrift to version 0.23.0 or later immediately. This is the vendor-released patch that addresses the bounds validation issue in the C++ JSON skip() function. Organizations unable to immediately patch should implement network-level controls restricting access to Thrift service endpoints to trusted internal networks only, and disable JSON protocol handling if alternative serialization protocols (Binary, Compact) are sufficient for their use case. If Thrift services must remain exposed, implement input validation and size limits at the application layer before JSON parsing.
