After applying the appropriate fix, additional instructions are needed for the CVE-2014-3500, CVE-2014-3501 and CVE-2014-3502 issues.
Complete the following steps to modify the Cordova allowlist
Note: One of the security fixes involves creating a new allowlist for protocols other than HTTP and HTTPS. If your application uses other protocols besides http and https, such as sms, mailto, geo, etc, then you need to make some configuration changes to add these protocols to the allowlist.
Procedure:
- Open the Cordova config.xml file, located in <project>/config.xml
- View your allowlist entries, such as the following example:
<access origin="https://my.company.com/resources" />
<access origin="http://*.othersupplier.com" />
- For every non HTTP or HTTPS protocol that you use you will need to add a allowlist entry like this code:
<access origin="sms://*" launch-external="true" />
<access origin="mailto://*" launch-external="true" />
<access origin="geo://*" launch-external="true" />
The launch-external attribute tells Cordova to allow this URL to be handled by other applications in Android system and not by the currently running Cordova. This approach means that when a user clicks a<a href="sms:555...">link, Android lets whatever application is registered to sms: handle the request.
The only entry in your allowlist might look like this code:
<access origin="*" />
In this instance, your application allows resource requests to any Internet resource, which might open your application to certain kinds of attacks. You should list specific domains in this tag that you want to be able to access.
If you do not utilize any protocol other than file, data, and content, then you can leave your allowlist as-is as these protocols are essential for Cordova internals and do not need to be explicitly allowlisted. All actions that use protocols that are not added to the allowlist are treated as no-ops and ignored by Cordova.
- Rebuild your application and redeploy to your users
After making these changes to the allowlist (if they are needed) then you will need to rebuild your Android application and distribute to your users as an update.
