CVE-2020-7864Network attack vector

Unauthenticated code execution via manipulated upload parameters

Published Jun 15, 2021 · Updated Sep 16, 2024

Unrestricted file upload in RAONWIZ DEXT5 Editor before 3.5.1405747.1100.03 allows remote attackers to execute code without authentication. KrCERT reports that parameter manipulation bypasses authentication and permits file upload, but does not identify the affected handler or parameter. A reachable server-side upload handler is required, and successful exploitation runs attacker-supplied code in the server context.
