Many businesses and individuals use Beaver Builder to quickly and efficiently develop professional-looking web pages. Web hosting providers and digital agencies also utilize this tool for rapid site development. Its accessibility and ease of use make it a favorite among both seasoned developers and newcomers.

The vulnerability detected by this scanner pertains to improper file process issues in the Beaver Builder Page Builder plugin. This type of vulnerability is due to improper access restrictions in source files, which can lead to unauthorized file access. Such vulnerabilities can expose the path of server files, which can be leveraged by attackers for further exploitation of the site. This scanner specifically looks for patterns in code execution errors that indicate an improper file handling process. The detection is critical as it can provide attackers insights into server structure. This vulnerability can be found on websites using the specific plugin in their WordPress installations.

Technically, the vulnerability involves the retrieval of the full path of server files through the improper handling of access to certain plugin files. An attacker can execute a GET request to specific paths to exploit this. For instance, the file "fl-builder.php" within the plugin directory can be accessed without proper authorization. When accessed, it may throw errors that expose full server paths and specific file information. The matchers in the scanner detect a successful exploit by identifying particular error messages and status codes in the HTTP response. This vital information allows attackers to understand more about the server configuration.

When exploited, this vulnerability can lead to several possible effects detrimental to the security of a website. Attackers obtaining the server file paths can use this knowledge to identify and leverage additional vulnerabilities in the system. It may assist in crafting more targeted attacks, potentially leading to unauthorized access or data breaches. Such exploits can result in data exposure, defacement of websites, or service disruption. The information gained may also facilitate entry for malware, further compromising the site's integrity and reliability. Ultimately, this vulnerability weakens the defense against cyber threats, emphasizing the need for robust security controls.
