Description

The WpMobi plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.0.3. This is due to missing or incorrect nonce validation on the handleSaveGeneralSettings function. This makes it possible for unauthenticated attackers to modify the plugin's General Settings and inject arbitrary web scripts into the administrator's browser via the unescaped app_name attribute reflection via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The injected script executes even when the supplied app_name value fails validation and is not persisted to the database, because the form is re-rendered with the attacker-supplied in-memory value on validation failure.
