Parameter Value
CVSS 9.8 (CRITICAL)
Affected Versions before 0.10.2
Type CWE-502 (Deserialization of Untrusted Data)
Vendor Internlm
Public PoC No

LMDeploy is a toolkit for compressing, deploying, and serving large language models. Starting in version 0.9.1 and prior to version 0.10.2, the LMdeploy implements an rpc server (AsyncRPCServer in zmq_rpc.py) for supporting the RPC communications. In its core functionality call_and_response(), I found it will directly use the pickles.loads() to deserialize the received messages without any sanitization, hence resulting in a remote code execution vulnerability by this RPC server.

Version 0.10.2 contains a patch.
