WordPress WPForms Full Path Disclosure Scanner

WordPress WPForms is a popular WordPress plugin used by bloggers, businesses, and developers to create forms on their websites. It simplifies form building and allows users to add various types of forms like contact forms, feedback forms, and more without needing to code. WPForms is integrated into WordPress sites to enhance user interaction and data collection. Organizations and individuals alike use this plugin to streamline processes and gather insights. The plugin's versatility makes it a top choice in the WordPress community for site engagement. It is often used where user input is required on WordPress websites.

The vulnerability detected in WPForms relates to publicly accessible files that lack proper ABSPATH protection, which can expose sensitive server path information. This occurs due to incorrect configurations where PHP files can be accessed directly. When these files are accessed, they can leak sensitive system paths through PHP error messages. Proper configuration and file access settings are crucial to ensure server paths remain hidden. The exposure arises particularly when error messages are thrown, providing unnecessary insights into the server infrastructure. This misconfiguration thus represents a security gap that attackers could exploit to gain information about the server's internal structure.

Technical details of the vulnerability include accessing endpoints like "/wp-content/plugins/wpforms-lite/src/Frontend/Modern.php" which reveal PHP error messages when directly accessed. Parameters leading to exposure include ABSPATH protection settings in WordPress configurations. The matcher in the detection mechanism checks for typical error indications such as "Fatal error" or "Warning," along with HTTP status codes. The presence of "wpforms-lite" in the response confirms successful vulnerability checking. Proper endpoint and parameter protection in plugin configurations is pivotal for preventing this information leakage.

Exploitation of this security misconfiguration can lead to potential information disclosure where attackers gain insights into server structure. By acquiring system paths, attackers may find ways to explore further vulnerabilities or plan targeted exploits. Such exposures compromise the website's security posture by making it easier to navigate server architecture. Unauthorized knowledge of server paths could assist in deploying more effective cross-site attacks. The resultant server information can also contribute to a broader reconnaissance effort by malicious entities. Correct insulation against such disclosures is necessary to maintain a sound security environment.
