WordPress bbPress Plugin Information Disclosure Scanner

WordPress bbPress Plugin is a widely-used extension for WordPress, adding functionalities for forum creation and management to websites. It is utilized by web developers and site administrators who want to integrate forums into their WordPress sites. This plugin allows users to engage in discussions, share ideas, and provide support on web platforms. Being open-source, it's favored for its customization capacity and community support. The plugin is especially beneficial for community-driven websites, enabling seamless forum integration and management. Its robust architecture and user-friendly interface make it popular among small to medium-sized websites.

The identified vulnerability relates to the disclosure of full path information within the plugin. It allows potential attackers to view internal file paths by accessing specific URLs directly. This type of vulnerability can reveal sensitive directory structures to unauthorized users. Such exposure may allow adversaries to craft subsequent attacks or attempt unauthorized file access. The vulnerability indicates misconfigurations or inadequate access restrictions within the plugin's code. As it exposes critical system information, it poses a risk to the site's security.

From a technical perspective, the vulnerability is triggered when an unauthorized user accesses the 'single-forum.php' file directly. The direct access leads to the output containing internal paths, especially when a "Call to undefined function" error occurs. The vulnerability is located in the 'extras' folder, under the plugin's templates directory. Verification of this flaw includes checking for specific error messages accompanied by file path disclosure. Such endpoints are exploited due to the lack of secure coding practices in file handling and error management. These technical loopholes emphasize the need for stronger access controls and error handling within the plugin.

Exploitation of this vulnerability could lead to a range of adverse outcomes. Unauthorized users could use disclosed paths to enumerate files or directories, paving the way for further attacks. Attackers can leverage this information for local file inclusion, path traversal, or other file-based attacks. Such exploits could compromise the confidentiality and integrity of the web server. The vulnerability might lead to unauthorized access to sensitive files if further exploited. Ultimately, this could result in data breaches and unauthorized information disclosure.
