WordPress DB Backup Directory Listing Due to Insecure Default Configuration Scanner

The WordPress DB Backup Plugin is used for creating database backups within the WordPress content management framework. It is typically deployed by website administrators and developers who require routine data archiving to ensure redundancy and recovery capabilities in case of data loss. The plugin is particularly useful for non-technical users because it simplifies the database backup process directly within the WordPress dashboard. This utility plays a critical role in protecting website data, crucial for any business or personal websites that store dynamic content. Additionally, it's applied on various scales, from small personal websites to larger commercial sites with significant database interactions. The overarching purpose is to preserve website databases in a format that is both easily restorable and manageable.

The detected vulnerability involves directory listing due to insecure default configuration, which unintentionally reveals database backup files. This exposure makes sensitive data accessible, which should ordinarily be hidden from unauthorized parties. Directory listing can permit attackers to browse directories on the server, gaining insight into structure and content, including .sql files. The existence of index pages that expose directory contents without requiring authentication poses significant risks. Often, vulnerabilities like these arise due to default settings that are meant to ease development and testing but not removed in production environments. Without necessary safeguards, such misconfigurations can be a simple but profound flaw leading to data breaches.

Technically, the potential vulnerability occurs when the backup directory within the plugin is indexed without appropriate access controls. If a web server doesn't forbid directory listing by default, or if file permissions are misconfigured, all contents, including database backups, are exposed. The endpoint "/wp-content/uploads/database-backups/" becomes accessible, showcasing every backup file with standard HTTP methods. The "Index of /" and file extensions ".sql" serve as markers for directory exposure, leading security testers or malicious actors directly to sensitive data. Moreover, this condition often returns HTTP status code 200, indicating the server successfully processed the request, further validating the directory's availability. Integrators must ensure server configurations align with security best practices to prevent such exposures.

Exploitation of this vulnerability could lead to unauthorized access to complete database files, containing sensitive information like usernames, hashed passwords, and configuration details. These files, when accessed by malicious actors, provide comprehensive insights into the database schema and allow the possibility of extracting data for further exploitation. Additionally, the exposed directories can divulge development or deployment flaws, potentially leading attackers to discover other vulnerabilities or weaknesses in the network. Consequently, data integrity, confidentiality, and system availability may be compromised, resulting in data theft, site defacement, or even further intrusion into the application environment.
