CVE-2023-6825 Scanner

WordPress File Manager is a plugin used by WordPress site administrators to manage files directly from the WordPress dashboard. It allows users to upload, edit, delete, and organize files from within the WordPress admin area. This plugin is popular among users who want an easy-to-use interface for their file management needs, avoiding the hassle of using FTP. Both free and Pro versions exist, offering varying levels of features to cater to different needs of website administrators. The plugin is often used to manage themes, plugins, and other WordPress files, making it a vital tool for maintaining WordPress sites. However, it's important that such tools remain secure to prevent unauthorized access or data exposure.

Directory Traversal is a vulnerability that can allow attackers to access arbitrary directories and files on a server beyond the web root folder. This vulnerability enables attackers to exploit the file path input fields to traverse directories, potentially granting them access to sensitive files. The issue arises from improper validation of user-supplied input data, which allows path traversal sequences to bypass security restrictions. As a result, attackers can read or even upload malicious files to locations where they should not have access. Directory Traversal is critical because it can lead to data exposure, data tampering, or full server compromise. Mitigating such vulnerabilities is crucial for maintaining the security and integrity of affected systems.

The technical details of this vulnerability involve the misuse of the 'target' parameter in the mk_file_folder_manager_action_callback_shortcode function. By exploiting this, attackers can traverse directory paths and access files outside the designated boundaries intended by the application. Attackers can manipulate the parameter to inject path traversal sequences, bypassing typical security mechanisms to access unauthorized files. This vulnerability requires administrator privileges in the free version of the plugin, but lower-level users can exploit it in the Pro version. The issue stems from insufficient sanitization of user input, which fails to restrict directory traversal patterns adequately. This oversight allows malicious actors the flexibility to reach sensitive sections of the server's file system.

When exploited, this vulnerability can lead to severe information disclosure, putting sensitive data at risk. Attackers might read passwords, configuration files, or other data critical to the application's security. It could also allow them to upload malicious files, possibly leading to malware infection or further exploitation of the server. The security breach might compromise the server entirely, exposing internal networks and potentially spreading across connected systems. Such an exploit can damage both the website's integrity and its user's trust, leading to significant financial and reputational losses. Therefore, timely patching and updating of vulnerable plugins are imperative to thwart potential attacks.
