Authenticated system access via unfiltered user fields
Published Apr 3, 2024 · Updated Nov 4, 2025
Improper input validation in OAS Platform 19.00.0057 allows remote authenticated users to gain system access through user configuration. The Config_SetProperties handler stores unfiltered SecurityGroup and Field1 through Field4 values, allowing an SSH key to be written to a strategic path. OAS Engine administrator credentials are required; successful exploitation grants access to the underlying host without reported confidentiality or service-interruption effects.
