WordPress Twenty Seventeen Theme Full Path Disclosure Scanner

The WordPress Twenty Seventeen Theme is widely used by bloggers and small businesses due to its clean design and customizability. It offers several front-page sections, featured images, and a great layout flexibility, making it versatile for various content types. Developed by Automattic, it's built with the purpose of providing an intuitive building experience for non-technical users. Known for its responsive design, the theme is compatible across devices, ensuring an optimal viewing experience for website visitors. It integrates seamlessly with various WordPress plugins, providing extended functionalities and features for website developers. This theme continues to be popular thanks to its sleek appearance and ease of use, catering to both novice and experienced WordPress users.

The Full Path Disclosure (FPD) vulnerability allows attackers to determine the absolute path of certain files in the server directory. Unauthorized file paths can be revealed through improper configuration or insufficient protection against direct file access. In this case, the WordPress Twenty Seventeen theme demonstrates such a misconfiguration. When specific theme files are accessed directly, sensitive path information can be leaked through error messages. This vulnerability provides useful information to potential attackers, aiding in further complex attacks against the target server. Addressing FPD is critical as it forms an entry-level penetration attempt by malicious entities.

The Full Path Disclosure vulnerability exploits the weak access controls on the theme's PHP files. When directly accessed, these files generate PHP error messages that reveal the server's file path. This often happens due to a lack of the `ABSPATH` protection that prevents direct access to PHP scripts. The vulnerable endpoint is the theme's directory path, particularly within `/wp-content/themes/twentyseventeen/inc/`. When the server responds with error details, it exposes sensitive directory paths, which can be harvested for use in additional harmful exploits. Identifying and remediating such file exposure is essential for maintaining server integrity and reducing risks.

Exploitation of this vulnerability can have several implications for the host site. Attackers could use the gathered path information to conduct directory traversal attacks, locate sensitive files, or develop more devastating backdoor entries. It might also facilitate remote code execution attempts if coupled with other vulnerabilities. Beyond unauthorized access, attackers could manipulate or replace essential files, disrupt services, or steal sensitive information. This ultimately leads to compromised site security, potential data breaches, and reputational damage for site owners.
