This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Apps and Samsung WatchOn. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of the WebView JavaScript Bridge. The issue lies in the ability to execute arbitrary commands from JavaScript. This can be chained with the ability to install arbitrary packages to execute code under the context of the current user.
