WordPress Rank Math SEO Plugin Improper File Process Scanner

The WordPress Rank Math SEO Plugin is utilized by website administrators and developers to enhance the search engine optimization of their WordPress sites. This plugin is popular for its comprehensive SEO tools that help users optimize their sites to improve searchability and visibility on search engines like Google. It provides features such as keyword analysis, SEO audits, and optimization for social media, making it a preferred choice for bloggers, content creators, and online businesses. The vulnerability detected within this plugin involves the potential exposure of sensitive file paths, which could be leveraged by attackers to gain insights into the site's file structure. Such exposure comes from direct access to certain files, potentially informing bad actors of critical system paths. This vulnerability highlights the importance of securing direct access to plugin files to mitigate possible exploitation.

The vulnerability associated with this plugin involves improper file processes, specifically the exposure of full path files through direct access. This issue may arise when insufficient access controls allow unauthorized users to view detailed error messages or directory structures. The vulnerability could provide attackers with information about the server's file paths and configurations, facilitating further attacks. Information gathered through this vulnerability could include server paths that may lead to other confidential files or systems. Such vulnerabilities are common in applications that do not enforce strict access controls or error message sanitization. Detection of this vulnerability can prevent unauthorized insight into server structures and help maintain the integrity of sensitive files.

Technically, this vulnerability is based on the improper management of file access within the plugin. The vulnerability surfaces when files such as class-helper.php, class-admin.php, and developer.php in the plugin's directory are accessed directly. These files, when accessed improperly, may disclose the full path information through error messages if not handled securely. Proper access checks are not invoked when direct URL access is attempted, leading to revealing fatal errors and path information. The vulnerable endpoints are primarily within the '/wp-content/plugins/seo-by-rank-math/includes/' directory. These endpoints should be either restricted or adequately handled to prevent unauthorized information exposure. This issue is compounded if user interactions with these endpoints lead to detailed error dumps, which detail file paths and system-specific information.

When exploited, this vulnerability can lead to serious security implications. Attackers can leverage disclosed path details to explore other parts of the system, potentially leading to unauthorized access or data exposure. Such exploits can be precursors to more severe breaches such as privilege escalation or data theft. By knowing the exact server paths, attackers can create a roadmap to navigate through the file system, evading security mechanisms. Additionally, this vulnerability could aid in reconnaissance for targeted attacks, increasing the risk of tailored exploits against known software configurations. Protecting against such threats requires attention to access controls and error message management to minimize information leakage.
