GHSA-HJW9-7F25-8H43

Vulnerability from github – Published: 2026-10-23 09:31 – Updated: 2026-10-23 09:31

Details

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

Severity

9.4 (Critical)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
