WordPress LazyLoad Plugin Full Path Disclosure Detection Scanner

The WordPress LazyLoad Plugin is a popular tool used by website developers and administrators to optimize website load times by lazily loading images. It is widely adopted across WordPress sites for its ease of integration and effectiveness in improving site performance. The plugin primarily finds use in content-heavy websites where images can slow down the initial page loading speed. Website owners who seek improved user experience frequently employ such performance-enhancing plugins. By managing image loads effectively, the plugin aids in reducing server load and enhancing front-end performance.

The vulnerability in focus is a security misconfiguration within the WordPress LazyLoad Plugin. It occurs because certain plugin files are publicly accessible without proper protection. This flaw results in the exposure of sensitive server path information through PHP error messages. The vulnerability is characterized by its potential to disclose server paths if the plugin's files are accessed directly, making critical system paths visible. Such exposures can aid potential attackers in crafting advanced attacks by revealing detailed server architecture details.

Technically, the vulnerability allows access to plugin files such as AdminPageSubscriber.php and LazyloadSubscriber.php, among others. These files lack adequate access control, thereby providing sensitive information upon direct access. The vulnerable endpoint typically involves GET requests to specific PHP files within the plugin, resulting in PHP error outputs. The functionality intended for administrative purposes may inadvertently lead to critical path exposure, especially if debug information is turned on server-side.

Exploitation of this vulnerability could significantly impact website security by unintentionally leaking server file paths. Knowing these paths, an attacker may exploit other vulnerabilities or weaknesses within the server infrastructure. Moreover, such exposed information can be the precursor to more severe security incidents, including measures to bypass or manipulate security controls. Therefore, safeguarding server paths against unauthorized disclosure is crucial in maintaining secure operations.
