CVE-2025-30047
CGM CLININET
Remote Code Execution via Java Deserialization in CGM CLININET
CVSS 4.0
9.4Critical
Official 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
