CVE-2023-2745 Scanner

WordPress Core is a widely utilized content management system (CMS) that powers millions of websites globally, ranging from personal blogs to large corporate sites. It offers a plethora of plugins and themes, allowing users to customize the look and functionality of their sites to suit individual or business needs. Given its popularity, WordPress is a common target for security vulnerabilities, making robust security practices essential when managing a site. The software is typically managed by website administrators or developers who are responsible for maintaining updates and system integrity. Its widespread use in hosting diverse functionalities makes it a versatile option for numerous digital projects and online services.

Directory Traversal is a vulnerability that allows attackers to gain unintended access to files and directories in a system by manipulating file paths within an application. This particular type of vulnerability poses significant risks as it can serve as an entry point for unauthorized data exposure or the execution of malicious activities. In the context of WordPress Core, this vulnerability can be exploited to access and load arbitrary translation files by using the 'wp_lang' parameter in requests. If exploited, it could further lead to additional attacks such as Cross-Site Scripting, especially if a crafted translation file is introduced into the system.

The Directory Traversal vulnerability in WordPress Core is primarily located at the 'wp_lang' parameter and affects versions up to and including 6.2. By appending path traversal characters to this parameter, an attacker can potentially retrieve sensitive WordPress configuration files such as 'wp-config.php'. This file contains vital information, including database credentials, which could be leveraged to gain deeper access to the application. The vulnerability stems from improper validation or sanitization of input paths, allowing traversal beyond the web root directory, and hence exposing files meant to remain inaccessible.

When exploited, this vulnerability can lead to unauthorized access to sensitive data, which could result in full compromise of the application or underlying server. Attackers could retrieve the database credentials, manipulate site contents and take over the website. Additionally, if complemented with other vulnerable points, it could lead to data manipulation, privilege escalation, or the deployment of malicious scripts to further infiltrate or disrupt the application. The potential for using this vulnerability as a stepping stone for other attacks makes it especially critical to address promptly.
