Summary
generated automatically from NVD dataInternLM LMDeploy versions 0.9.0 through 0.18.0 have an unauthenticated remote code execution flaw (CWE-502, insecure deserialization) in the /update_weights endpoint. A remote attacker can send a base64-encoded crafted pickle in the serialized_named_tensors field, which ForkingPickler.loads deserializes without validation. This lets the attacker run OS commands with the privileges of the api_server process. The flaw is rated CRITICAL with a CVSS v3.1 score of 9.8.
