WordPress History Collection is a plugin that adds functionality to WordPress websites by collecting and displaying page view histories. It is widely used by website administrators and bloggers who need detailed statistics about site visits. The plugin provides an easy-to-use interface to access these statistics directly from the WordPress dashboard. By enabling detailed analyses of visitor patterns, it aids in content strategy and website management. The plugin is especially useful for content-driven websites where understanding user behavior is crucial. Integration with existing WordPress installations is seamless, adding value without significant configuration overhead.

The Arbitrary File Download vulnerability allows attackers to download sensitive files from the server where the plugin is installed. This type of vulnerability is critical because it can expose confidential data, application configuration files, or sensitive server information. Exploiting this vulnerability requires constructing specific requests to the vulnerable endpoint, potentially allowing access to files containing sensitive content. This opens the opportunity for further attacks, such as exploiting credentials found in downloaded files. Ensuring the security of file operations is crucial to preventing such breaches.

The vulnerability is caused by inadequate validation of user-supplied input, specifically the file path parameters passed to the download script. The endpoint /wp-content/plugins/history-collection/download.php is particularly vulnerable because it fails to sanitize the input correctly. Attackers can use directory traversal techniques to access files outside the intended directory. By manipulating the 'var' parameter, attackers can craft requests to download arbitrary files from the server. The inclusion of special characters like ".." enables directory traversal, reaching sensitive files like wp-config.php.

Exploiting this vulnerability can lead to significant data breaches, as unauthorized users can access sensitive configuration files. This may result in unauthorized access to the database, where they can retrieve or alter data at will. Further, malicious actors could gain insights into the server's file structure and its security mechanisms. Successful exploitation poses a risk of data leaks, service disruptions, or even full server compromise if additional security measures are not in place. Organizations might face financial, reputational, and compliance challenges as a consequence.
