WordPress Download Shortcode Local File Inclusion Scanner

The WordPress Download Shortcode is utilized by website administrators and content creators to facilitate the easy download of files from their WordPress sites. It is specifically used within the WordPress platform, a popular content management system known for its flexibility and user-friendliness. The plugin serves the purpose of allowing users to add simple download buttons anywhere on their site via shortcodes, enhancing the site’s functionality. It is popular among developers and non-developers alike for simplifying the file management process within WordPress. By providing an intuitive interface, it makes file handling accessible to users of varying technical expertise. However, like many plugins, it requires regular updates and maintenance to ensure security and stability.

The Local File Inclusion (LFI) vulnerability detected by this scanner pertains to inadequate input sanitization within the WordPress Download Shortcode. This vulnerability can be exploited by a malicious actor to include and execute files on a server without proper authorization. The exploitation of this vulnerability might lead to unauthorized access to sensitive configuration files and critical information. If an attacker gains access, they could potentially cause disruptions or pave the way for further cyber attacks. The defect arises from how the plugin handles file paths, allowing for unintended directory traversal. Such vulnerabilities are common in applications that do not implement sufficient user input validation and sanitization measures.

Technically, this particular vulnerability affects the 'force-download.php' file within the plugin's directory. The parameter 'file' is particularly susceptible as it allows the inclusion of files via manipulated paths through directory traversal. When exploited, the vulnerable endpoint can expose sensitive files like 'wp-config.php', which may contain database credentials. The GET method is used in the attack, manipulating URL parameters to traverse directories and access unauthorized files. The presence of specific terms such as "DB_NAME" and "DB_PASSWORD" in response can confirm the vulnerability's exploitation. Ensuring that all user inputs are thoroughly sanitized is crucial in preventing such attacks.

If this vulnerability is exploited, it could lead to severe consequences for the affected WordPress website. Unauthorized access to config files can reveal sensitive information, including database credentials, leading to data theft or further server compromise. The exposure of such data could allow attackers to manipulate the site's database, insert malicious code, or even hijack the website entirely. Additionally, the unauthorized execution of script files could damage critical files and disrupt website functionality. The trustworthiness and reputation of the affected website could drastically decline, impacting business and user confidence.
