VAR-202102-0296
Vulnerability from variot - Updated: 2023-12-18 10:51A vulnerability has been identified in PCS neo (Administration Console) (All versions < V3.1), TIA Portal (V15, V15.1 and V16). Manipulating certain files in specific folders could allow a local attacker to execute code with SYSTEM privileges. The security vulnerability could be exploited by an attacker with a valid account and limited access rights on the system. Siemens Totally Integrated Administrator (TIA) fails to properly set the module search path to be used by a privileged Node.js component, which can allow an unprivileged Windows user to run arbitrary code with SYSTEM privileges. The PCS neo administration console is reported to be affected as well.CVE-2020-25238 AffectedCVE-2020-25238 Affected. TIA Administrator is a web-based framework that can contain different functional modules for management tasks, as well as functions for managing SIMATIC software and licenses.
Siemens TIA Administrator has a privilege escalation vulnerability

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.
