VAR-202311-0460

Vulnerability from variot - Updated: 2024-01-18 21:06

A vulnerability has been identified in SIMATIC PCS neo (All versions < V4.1). When accessing the Information Server from affected products, the products use an overly permissive CORS policy. This could allow an attacker to trick a legitimate user to trigger unwanted behavior. Siemens' SIMATIC PCS neo contains an overly permissive cross-domain whitelisting vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. SIMATIC PCS neo is a distributed control system (DCS)

Detection rules are retrieved from Rulezet.

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.
