Title
Grid Protection Alliance openPDC and openHistorian Use of Externally-Controlled Input to Select Classes or Code
Summary
A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load. An attacker with an authenticated user account and the ability to place a file on the host filesystem can use this to run arbitrary constructor code, and this code runs with the privileges of the affected service account.

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.
