How the Exploit Works

The vulnerability resides in the wf_get_cookie shortcode of the FunnelKit plugins. It allows an authenticated attacker with contributor-level access to request and extract sensitive data, including authentication cookies of other site users. By obtaining these cookies, attackers can impersonate legitimate users and potentially escalate their privileges within the system. This could lead to unauthorized actions, including data leakage or full system compromise.

Conceptual Example Code

The following is a simplified, conceptual example of how the vulnerability might be exploited through a HTTP request:

GET /wp-admin/admin-ajax.php?action=wf_get_cookie&user_id=TARGET_USER_ID HTTP/1.1
Host: target.example.com
Cookie: wordpress_logged_in_[hash]=attacker's_cookie

In this example, the attacker makes a GET request to the vulnerable endpoint, passing the targeted user’s ID as a parameter. The attacker’s session cookie is included in the request, which is then processed by the server, potentially returning the authentication cookies of the targeted user.
Please note that the exploitation of this vulnerability requires authenticated access to the target system. Therefore, the attacker would first need to gain some level of access, typically as a contributor, before they can leverage this vulnerability. This underlines the importance of strong password policies and user account management in mitigating the risk of such attacks.

Mitigation Guidance

In light of this vulnerability, it is recommended to apply a vendor patch to the affected plugins as soon as possible. If a patch is not immediately available or cannot be applied in a timely manner, deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to block or alert on attempts to exploit this vulnerability, thereby reducing the risk of an attack.
In the long term, regular software updates, strong password policies, and stringent account management practices are key strategies to prevent such vulnerabilities from being exploited.
