Authenticated code execution via arbitrary file upload
Published May 25, 2022 · Updated Apr 15, 2025
Arbitrary file write in Open Automation Software OAS Platform 16.00.0112 allows remote authenticated users to execute code through TCP requests. The OAS Engine's SecureTransferFiles command accepts an attacker-chosen destination path and writes uploaded content anywhere permitted to the service account. Exploitation requires OAS File Transfer privileges or captured OAS credentials; the demonstrated path replaces the service user's SSH authorized_keys file and yields that account's access.
