Service interruption or data alteration via request replay

Published Jun 19, 2023 · Updated Dec 9, 2024

Capture-replay in SUBNET PowerSYSTEM Center 2020 U10 and earlier allows remote authenticated users to disrupt service or alter data. The application accepts previously captured authenticated requests without anti-forgery tokens, permitting the same privileged operation to be submitted again. Exploitation requires high privileges and an adjacent network position; the published impact is limited to data integrity loss or service interruption.
