CVE-2017-20037Network attack vector

Authenticated privilege escalation via manipulated c parameter

Published Jun 11, 2022 · Updated Apr 15, 2025

Improper privilege management in SICUNET Access Controller 0.32-05z allows remote authenticated users to gain elevated privileges. Public records identify manipulation of the c argument but do not disclose the affected function or how that input bypasses privilege enforcement. Network access with an existing low-privilege account is required, and the resulting role or permitted controller actions remain undisclosed.
