Demo Examples

Origin Validation Error

CWE-346

This Android application will remove a user account when it receives an intent to do so:


               
}
}
destroyUserData(userID);

This application does not check the origin of the intent, thus allowing any malicious application to remove a user. Always check the origin of an intent, or create a whitelist of trusted applications using the manifest.xml file.

Origin Validation Error

CWE-346

These Android and iOS applications intercept URL loading within a WebView and perform special actions if a particular URL scheme is used, thus allowing the Javascript within the WebView to communicate with the application:


               
}// Android
}
}
return false;
return true;

               
}// iOS
return YES;
return NO;
UIWebView *webView = [self writeDataToView:[URL query]];// Make data available back in webview.

A call into native code can then be initiated by passing parameters within the URL:


               
window.location = examplescheme://method?parameter=value

Because the application does not check the source, a malicious website loaded within this WebView has the same access to the API as a trusted site.
