CVE-2024-11350: AdForest Privilege Escalation Vulnerability

CVE-2024-11350 Overview

CVE-2024-11350 is a critical privilege escalation vulnerability affecting the AdForest theme for WordPress. The vulnerability exists in all versions up to and including 5.1.6 and allows unauthenticated attackers to take over any user account, including administrator accounts, by exploiting improper identity validation in the password reset functionality.

Critical Impact

Unauthenticated attackers can change any user's password, including administrators, enabling complete site takeover without requiring prior authentication or user interaction.

Affected Products

• AdForest WordPress Theme versions up to and including 5.1.6
• Scriptsbundle AdForest classified WordPress theme

Technical Details for CVE-2024-11350

Vulnerability Analysis

This vulnerability is classified under CWE-640 (Weak Password Recovery Mechanism for Forgotten Password). The AdForest theme implements a custom password reset mechanism through the adforest_reset_password() function that fails to properly validate the identity of the user requesting the password change. This architectural flaw allows unauthenticated attackers to bypass normal authentication controls and directly modify user credentials.

The vulnerability requires no privileges or user interaction to exploit, making it particularly dangerous for WordPress sites using this theme. An attacker can target any user account on the system, including those with administrative privileges, leading to complete compromise of the WordPress installation.

Root Cause

The root cause of this vulnerability lies in the adforest_reset_password() function's failure to implement proper user identity verification before allowing password modifications. The function does not adequately confirm that the person initiating the password reset request is the legitimate account owner or has proper authorization to perform the action.

This represents a broken access control issue where the password reset mechanism trusts user-supplied input without sufficient validation, allowing attackers to manipulate the process to change passwords for arbitrary accounts.

Attack Vector

The attack can be executed remotely over the network without authentication. An attacker identifies a target WordPress site using the vulnerable AdForest theme, then crafts malicious requests to the adforest_reset_password() function to change the password of a targeted user account.

The exploitation flow typically involves:

1. Identifying the password reset endpoint exposed by the AdForest theme
2. Manipulating request parameters to specify a target user account
3. Bypassing identity verification due to improper validation
4. Successfully changing the target user's password to attacker-controlled credentials
5. Logging in with the new credentials to gain access to the compromised account

For administrator accounts, this results in complete site takeover with the ability to install malicious plugins, modify content, access sensitive data, and potentially compromise the underlying server.

Detection Methods for CVE-2024-11350

Indicators of Compromise

• Unexpected password reset activity in WordPress logs, particularly for administrator accounts
• Unusual login attempts or successful logins following password changes that weren't initiated by legitimate users
• Modifications to user account credentials without corresponding user-initiated password reset emails
• New or modified administrator accounts appearing in the WordPress user database

Detection Strategies

• Monitor WordPress authentication logs for anomalous password reset requests and subsequent successful logins
• Implement alerting on password changes for privileged accounts that don't follow normal reset workflows
• Review web server access logs for suspicious requests targeting AdForest theme endpoints, particularly those related to password functionality
• Deploy Web Application Firewall (WAF) rules to detect and block exploitation attempts targeting the adforest_reset_password() function

Monitoring Recommendations

• Enable detailed logging for all authentication-related activities in WordPress
• Configure real-time alerts for administrator account modifications or password changes
• Implement user activity monitoring to detect unauthorized access following account takeover
• Regularly audit user accounts for unexpected changes or newly created privileged accounts

How to Mitigate CVE-2024-11350

Immediate Actions Required

• Update the AdForest theme to a version newer than 5.1.6 immediately
• Audit all user accounts, especially administrators, for unauthorized password changes or suspicious activity
• Force password resets for all administrator accounts as a precautionary measure
• Review recent access logs for signs of exploitation and unauthorized access

Patch Information

Organizations using the AdForest theme should update to the latest patched version available from the vendor. The vulnerability affects all versions up to and including 5.1.6. Refer to the ThemeForest Product Page for the latest version and update instructions. Additional technical details about this vulnerability are available in the Wordfence Vulnerability Report.

Workarounds

• If immediate patching is not possible, consider temporarily disabling the AdForest theme's password reset functionality
• Implement additional authentication controls such as two-factor authentication (2FA) for all administrator accounts
• Deploy a Web Application Firewall with custom rules to block requests to the vulnerable password reset endpoints
• Restrict access to WordPress admin areas by IP address where feasible
• Consider temporarily switching to a different theme until the update can be applied
