CVE-2023-0882Network attack vector

Privilege abuse via RDP proxy object reference

Published Feb 17, 2023 · Updated Jun 1, 2026

Authorization bypass in Kron Technologies Single Connect 2.16 allows remote authenticated users to abuse RDP proxy privileges. The RDP proxy accepts a user-controlled object identifier without verifying that the requesting account is authorized for the referenced resource. A valid low-privileged account and network access to the proxy are required; public records do not identify the exact resource or privileged action.
