Published Aug 5, 2021 · Updated Aug 4, 2024

Improper input validation in RAONWIZ RAON K Upload 2018.0.2.55 allows remote attackers to execute commands through a crafted web page. An undisclosed method accepts an attacker-controlled parameter as the command to run without sufficient validation. Execution occurs as the current user and requires viewing the page in Internet Explorer running with administrator privileges because of cross-domain policy.
