Description
An OS command injection vulnerability exists in multiple Raidsonic NAS devices—specifically tested on IB-NAS5220 and IB-NAS4220—via the unauthenticated timeHandler.cgi endpoint exposed through the web interface. The CGI script fails to properly sanitize user-supplied input in the timeZone parameter of a POST request, allowing remote attackers to inject arbitrary shell commands.
