CVE-2024-11087: Miniorange Social Login Auth Bypass Flaw

CVE-2024-11087 Overview

The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) Pro Addon plugin for WordPress contains a critical authentication bypass vulnerability affecting all versions up to and including 200.3.9. The vulnerability exists due to insufficient verification on the user being returned by the social login token, allowing unauthenticated attackers to log in as any existing user on the site, including administrators.

Critical Impact

Unauthenticated attackers can bypass authentication and gain unauthorized access to any user account, including administrator accounts, potentially leading to complete site compromise.

Affected Products

• miniOrange Social Login and Register Pro Addon for WordPress versions up to and including 200.3.9
• WordPress sites using miniOrange Social Login with social authentication providers (Discord, Google, Twitter, LinkedIn)
• Any WordPress installation with vulnerable miniOrange social_login plugin versions

Technical Details for CVE-2024-11087

Vulnerability Analysis

This authentication bypass vulnerability stems from a fundamental flaw in how the miniOrange Social Login Pro Addon plugin validates social login tokens. When a user authenticates via a social provider (Discord, Google, Twitter, or LinkedIn), the plugin fails to adequately verify that the user returned by the social login token matches the intended authenticated user.

The vulnerability is particularly dangerous because it requires no authentication to exploit and can be executed remotely over the network. An attacker only needs to know the target username and ensure the victim does not already have an account linked to the social service being exploited for the token return.

Root Cause

The root cause of CVE-2024-11087 is classified under CWE-287 (Improper Authentication). The plugin does not properly validate the binding between the social login token and the WordPress user account. This insufficient verification allows an attacker to manipulate the authentication flow to associate a social login token with an arbitrary user account rather than the legitimate account owner.

The plugin's token validation logic trusts the social provider's response without adequately confirming that the returned user identity corresponds to the WordPress user being authenticated, creating a trust boundary violation.

Attack Vector

The attack vector for this vulnerability is network-based and requires no privileges or user interaction. An attacker can exploit this vulnerability under the following conditions:

1. The target WordPress site has the vulnerable miniOrange Social Login Pro Addon plugin installed and active
2. The attacker knows a valid username on the target site (such as admin or other administrator usernames)
3. The target user does not have an existing linked account for the social service being exploited

The attack works by intercepting or manipulating the social login token verification process to associate an attacker-controlled social login with a victim's WordPress account. Once successful, the attacker can authenticate as the victim user with full access to their account privileges.

Detection Methods for CVE-2024-11087

Indicators of Compromise

• Unexpected administrator logins from unfamiliar IP addresses or geographic locations
• User accounts suddenly linked to new social login providers without user initiation
• Authentication logs showing social login activity for high-privilege accounts that don't typically use social authentication
• Multiple failed or successful social login attempts targeting administrator usernames

Detection Strategies

• Monitor WordPress authentication logs for social login events, particularly targeting administrator or high-privilege accounts
• Implement alerting for new social provider account linkages on existing user accounts
• Review web server access logs for unusual patterns in OAuth callback URLs associated with the miniOrange plugin
• Deploy Web Application Firewall (WAF) rules to detect and block anomalous social login token manipulation attempts

Monitoring Recommendations

• Enable detailed logging for the miniOrange Social Login plugin authentication events
• Configure SIEM alerts for authentication bypass patterns including rapid account access changes
• Monitor for unauthorized plugin configuration changes or new user account creations following social login events
• Regularly audit user accounts for unexpected social provider linkages

How to Mitigate CVE-2024-11087

Immediate Actions Required

• Update the miniOrange Social Login and Register Pro Addon plugin to the latest patched version immediately
• Audit all administrator and privileged user accounts for unauthorized social login linkages
• Review recent authentication logs for signs of exploitation
• Consider temporarily disabling social login functionality until the patch is applied

Patch Information

Organizations using the miniOrange Social Login and Register Pro Addon plugin should update to a version newer than 200.3.9. Check the MiniOrange Security Solutions website for the latest security updates and patch information. The Wordfence Threat Intelligence Report provides additional details on affected versions.

Workarounds

• Disable the miniOrange Social Login Pro Addon plugin entirely until a patch can be applied
• Implement additional authentication controls such as multi-factor authentication (MFA) for administrator accounts
• Restrict social login capabilities to non-administrative user roles if plugin functionality is required
• Configure web server rules to limit access to social login callback endpoints to expected traffic patterns

# Configuration example - Disable social login via wp-config.php
# Add to wp-config.php to prevent social login plugin loading
define('MINIORANGE_DISABLE_SOCIAL_LOGIN', true);

# Alternative: Rename plugin folder to deactivate
# mv wp-content/plugins/miniorange-social-login-pro wp-content/plugins/miniorange-social-login-pro.disabled
