Laragon Configuration Disclosure Scanner

Laragon is an easy-to-use, fast, and dynamic development environment typically used by developers to build and test PHP applications. It's widely adopted for setting up web application environments due to its convenience and support for multiple types of software stacks. The platform provides users with a Windows-based WAMP stack that includes Apache, MySQL, and PHP, among other components. Laragon's goal is to allow developers to focus on development rather than environment setup, thus boosting productivity. It is often used in both educational settings for learning web development and in professional environments for prototyping. Its friendly GUI and wide-ranging support make it a popular choice among developers aiming for a streamlined setup.

The vulnerability is an Exposure vulnerability, resulting from improper handling where a publicly accessible phpinfo file is exposed. Exposure vulnerabilities occur when sensitive information is inadvertently made accessible to unauthorized entities. This phpinfo page can reveal valuable configuration details regarding the PHP environment, including installed modules and the PHP version, which could be leveraged by attackers to exploit known vulnerabilities or misconfigurations. The existence of such files accessible over the internet is a significant security oversight, often stemming from the default settings or testing configurations that were not updated post-deployment. Detecting such exposures is crucial to prevent potential information leaks that could help in launching targeted attacks.

From a technical standpoint, the vulnerability is identified by accessing the phpinfo page via a GET request, typically reachable under the path "/?q=info". If the page is accessible and returns a 200 OK status, it confirms the phpinfo file exposure. This page includes various diagnostic information about the PHP environment, which is not intended for public display. The template relies on specific keywords such as "PHP Extension" and "PHP Version" to validate the existence of a phpinfo page. Attackers can exploit this information to gather intelligence and search for additional vulnerabilities within the system or related technologies.

If this vulnerability is exploited by unauthorized individuals, it could lead to the compromise of sensitive information about the server configuration, which attackers can use to plan further attacks. For example, knowing the PHP version could allow attackers to exploit known vulnerabilities associated with that version. This can lead to unauthorized access, privilege escalations, and potential data breaches. It is vital to control access to such diagnostic and information pages to safeguard system and data integrity.
