WordPress Custom Post Type Full Path Disclosure Scanner

WordPress is a widely-used content management system for creating and managing websites. The Custom Post Type UI plugin allows users to create and manage post types and taxonomies for WordPress without needing code knowledge. This plugin is used by developers to enhance functionality and organization of WordPress sites. It is leveraged in business, blogs, portfolios, and e-commerce sites for its flexibility and ease of use. The wide adoption of this plugin makes it a popular choice for expanding WordPress functionalities. Given its extensive usage, any vulnerability in this plugin can have widespread implications for WordPress-based websites.

The detected vulnerability in this scanner relates to Information Disclosure, specifically a Full Path Disclosure (FPD). This occurs when sensitive information about the file system and the web application's directory structure is exposed. This can provide an attacker with details about the server configuration aids in further attacks. Full Path Disclosure is often an unintended consequence of improper error handling that reveals system information. In WordPress Custom Post Type UI, internal file system paths may be disclosed due to direct file access. Such disclosures can lead to enhanced attack strategies and exploitation by attackers.

The technical details indicate that visiting certain plugin endpoints can result in the server exposing file paths. Specifically, this vulnerability is triggered when accessing the URL 'wp-content/plugins/custom-post-type-ui/custom-post-type-ui.php'. The response may contain error messages or warnings that inadvertently disclose the server's internal directory structure. This information could be used to craft more sophisticated attacks against the system. The vulnerability requires no authentication to exploit, potentially making any WordPress site using the vulnerable plugin susceptible.

Exploitation of this vulnerability can have several potential effects. Attackers could use the disclosed path information to perform directory traversal attacks or search for other vulnerabilities in the web server. Such information also facilitates targeted attacks by revealing the technology stack and configuration specifics. Disclosing internal paths can help attackers in creating more targeted payloads in subsequent attacks. Additionally, it increases exposure to additional vulnerabilities when combined with other disclosed system information. Ultimately, it leads to increased risk of unauthorized access or data breaches.
