Quick assessment

Affected
InternLM lmdeploy
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

LMDeploy 是一个用于压缩、部署和提供服务的大语言模型工具包。从 0.9.1 版本开始，到 0.10.2 版本之前，LMdeploy 实现了一个 RPC 服务器（位于 中的 ）以支持 RPC 通信。在其核心功能 中，我们发现它直接使用 对接收到的消息进行反序列化，且未进行任何净化处理，从而导致该 RPC 服务器存在远程代码执行（RCE）漏洞。0.10.2 版本已包含修复补丁。

Vulnerability Title
LMdeploy has Remote Code Execution by Pickle Deserialization via zmq_rpc.call_and_response() in InterLM/lmdeploy
Source: CVE Program / CVE List V5
Vulnerability 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.
