CVE-2020-13532

NT SYSTEM execution via replaceable service binary

Published Apr 9, 2021 · Updated Aug 4, 2024

Incorrect default permissions in Ocean Data Systems Dream Report 5 R20-2 allow local users to gain NT SYSTEM via binary replacement. The default C:\ODS installation grants Everyone full control over the Syncfusion Dashboard Windows Service executable, allowing substitution with a malicious file. A user able to write locally to that executable gains system-level code execution when the service launches the replacement.
