AI risk analysis
- Summary
- The vulnerability in LMDeploy allows remote code execution due to improper deserialization of messages, posing a critical risk.
- Exploitability
- Exploitation is relatively straightforward as it requires sending maliciously crafted messages to the RPC server. The server must be running and accessible.
- Blast radius
- If exploited, this could lead to full compromise of the system hosting the RPC server, including potential data exfiltration and control of the server.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to version 0.10.2 or later.

NVD description
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.
