Vulnerability Data

LightLLM through 1.2.0 contains a denial of service vulnerability that allows unauthenticated attackers to crash the inference worker by supplying the internal pd_kv_trans_params field to the /generate endpoint. Attackers can send a single request whose parameters cause pickle.loads to fail…

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CA-8 Penetration Testing
addresses: CWE-502

Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.

SA-11 Developer Testing and Evaluation
addresses: CWE-502

Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.

SC-44 Detonation Chambers
addresses: CWE-502

Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.

SI-10 Information Input Validation
addresses: CWE-502

Validates or rejects untrusted serialized data before deserialization occurs.

SI-3 Malicious Code Protection
addresses: CWE-502

Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.

SI-7 Software, Firmware, and Information Integrity
addresses: CWE-502

Integrity verification of serialized information can detect tampering before deserialization occurs.

SR-4 Provenance
addresses: CWE-502

Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
