Severity
Summary
A vulnerability has been identified in SINEC NMS (All versions < V4.0 SP3), User Management Component (UMC) (All versions < V2.15.2.1). The affected application permits improper modification of a configuration file by a low-privileged user.
This could allow an attacker to load malicious DLLs, potentially leading to arbitrary code execution with SYSTEM privileges.(ZDI-CAN-28108)

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.
