WP-CLI Config Exposure Scanner

WP-CLI is a command-line interface for WordPress, used by developers and administrators to manage their WordPress sites more efficiently. It enables users to perform routine tasks such as updating plugins, configuring multisite installations, and migrating databases without needing a web browser. Its flexibility makes it a popular tool for WordPress development and site management in both small and large-scale environments. Used extensively by site administrators, security professionals, and developers, WP-CLI streamlines workflows by permitting automation of numerous WordPress tasks. Many hosting providers and web development agencies incorporate WP-CLI in their operations to provide efficient maintenance and deployment services.

The vulnerability detected by this scanner concerns the exposure of configuration files related to WP-CLI, such as the 'wp-cli.yml' file. This can occur when these files are unintentionally left accessible on the web server, exposing sensitive settings and directory structures to potential attackers. Configuration exposure can lead to unauthorized access to the configuration details and operational specifics of WP-CLI-managed websites. If these files contain improper permissions or are placed in publicly accessible directories, security and operational protocols might be compromised. This detection highlights a critical oversight in file management, necessitating careful scrutiny of access settings to prevent data leaks.

The technical detail of the vulnerability is focused on locating the 'wp-cli.yml' file, which, if present and unprotected, is checked by sending a HTTP GET request to the file's path. Match conditions include both the presence of specific strings such as "apache_modules:" and "mod_rewrite", and the HTTP status code 200, indicating successful retrieval. This combination ensures that the file not only exists but contains expected configurable WP-CLI data. The sensitivity lies in the fact that the file can automate management of WordPress installations, which if exposed, could disclose potential target areas for exploitation.

Possible effects of exploiting this vulnerability include compromise of site security and disruption of service due to unauthorized access to administrative functions. Attackers could use exposed configuration information to map out vulnerabilities or manipulate WP-CLI commands maliciously. This could lead to further attacks such as directory traversal, file manipulation, or even facilitating unauthorized changes on the WordPress site. The integrity and confidentiality of the WordPress installation are at risk, potentially leading to data breaches and compromised user accounts.
