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.

CGM CLININET 存在远程代码执行漏洞，该漏洞源于对不可信数据的反序列化操作。该服务器暴露了一个基于 HTTP 的 API，供管理模块使用，并通过 Java 对象序列化机制进行数据交换。位于同一局域网内的攻击者可向此 API 发送请求，并传输精心构造的序列化对象；当该对象被反序列化时，攻击者即可在服务器上以 root 权限执行任意代码。 该问题已在 2026.MS3 版本中修复。

Vulnerability Title
Remote Code Execution via Java Deserialization in CGM CLININET
Source: CVE Program / CVE List V5
Vulnerability Description
CGM CLININET is vulnerable to Remote Code Execution caused by deserialization of untrusted data. The server exposes an HTTP-based API, used by the administrative module, that exchanges data using Java object serialization. An attacker within the same local network is able to send requests to this API and transmit a crafted serialized object. When it is deserialized, it allows arbitrary code execution with root privileges on the server.  This issue was fixed in version 2026.MS3
