User Interaction: None
Impact: Unauthorized access to user accounts and potential system compromise or data leakage

How the Exploit Works
The vulnerability stems from the theme’s failure to correctly validate a user’s identity before updating their details, including the password. This omission allows an unauthenticated attacker to submit a request to change any user’s password, including administrators. Once the password is changed, the attacker can gain access to the user’s account, escalating their privileges to that of the targeted user.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. Here, a malicious HTTP POST request is made to the password update endpoint of the target server, forcing the update of an arbitrary user’s password:
POST /wp-admin/password-update HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_id": "admin", "new_password": "malicious_password" }In this scenario, the `user_id` field is set to the targeted user, and the `new_password` field is set to the attacker’s chosen password. Upon successful execution, the attacker would have full access to the targeted user’s account.
Mitigation Guidance
The most effective way to mitigate this vulnerability is by applying the vendor’s patch as soon as it becomes available. In the meantime, users can make use of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) to monitor and block suspicious activities. Also, implementing measures such as multi-factor authentication and regularly monitoring account activities can help reduce the risk of unauthorized access.
