CVE-2024-12402

Comprehensive Technical Analysis of CVE-2024-12402

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-12402

Description: The "Themes Coder – Create Android & iOS Apps For Your Woocommerce Site" plugin for WordPress is vulnerable to privilege escalation via account takeover. This vulnerability affects all versions up to and including 1.3.4. The issue arises from insufficient validation of a user's identity before updating their password through the update_user_profile() function. This allows unauthenticated attackers to change the passwords of arbitrary users, including administrators, thereby gaining unauthorized access to their accounts.

CVSS Score: 9.8

Severity Evaluation:

• Critical: The CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for complete system compromise, the ease of exploitation, and the lack of authentication required to exploit the vulnerability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker can exploit this vulnerability without needing any credentials, making it highly accessible.
• Password Reset: The attacker can change the password of any user, including administrators, by sending a crafted request to the update_user_profile() function.

Exploitation Methods:

• Direct Exploitation: An attacker can send a specially crafted HTTP request to the vulnerable endpoint, specifying the target user's ID and a new password.
