>                 URL: https://issues.apache.org/jira/browse/CB-9135
>             Project: Apache Cordova
>          Issue Type: Bug

> It can remote exploit Apache Cordova App's secondary configuration variables on Android.
> The details are in the following links:
> 1.http://cordova.apache.org/announcements/2015/05/26/android-402.html
> 2.http://blog.trendmicro.com/trendlabs-security-intelligence/trend-micro-discovers-apache-vulnerability-that-allows-one-click-modification-of-android-apps/
> However, the fix isn't complete. Using the following adb command, it can still crash
the Cordova App.
> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
> adb shell am start -n org.apache.mobilespec/.CordovaApp -es loadurltimeoutvalue "aaa"
> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
> The reason is that in CordovaWebView.java's loadUrlIntoView(final String url, boolean
recreatePlugins) mehtod, it try to get "loadurltimeoutvalue" value from Activity's intent
and then be parsed int using the following code.
> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
> final int loadUrlTimeoutValue = Integer.parseInt(this.getProperty("LoadUrlTimeoutValue",
"20000"));
> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
> However, if the value isn't a int type, such as "aaa", it will throw "java.lang.NumberFormatException",
and crash the App.
> The possible solution is to verify the value if it's a int type. If it's a valid int
type value, we can use the value, or ignore the value and use the default.
