CVE-2024-9105
Authentication Bypass Using an Alternate Path or Channel (CWE-288)
Summary
The UltimateAI plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.8.3. This vulnerability is due to insufficient verification of the user being supplied in the 'ultimate_ai_register_or_login_with_google' function. As a result, unauthenticated attackers can potentially log in as any existing user on the site, including administrators, if they have access to the email.
Impact
This vulnerability allows unauthenticated attackers to bypass authentication and gain unauthorized access to WordPress sites using the UltimateAI plugin. The potential impacts include: 1. Unauthorized admin access: Attackers could log in as administrators, gaining full control over the WordPress site. 2. Data breach: With admin-level access, attackers could steal sensitive information, including user data and confidential content. 3. Site manipulation: Attackers could modify site content, install malicious plugins, or deface the website. 4. Further exploitation: The compromised site could be used as a launching point for attacks on other systems or to distribute malware. Given the high CVSS base score of 9.8, this vulnerability is considered critical and could lead to a complete compromise of the affected WordPress sites.
Exploitation
There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.
Patch
A patch is not explicitly mentioned in the provided information. However, given that the vulnerability affects versions up to and including 2.8.3 of the UltimateAI plugin, it is likely that a patched version (2.8.4 or higher) has been or will be released. Website administrators should check for updates to the UltimateAI plugin and apply them as soon as they become available.
Mitigation
To mitigate this vulnerability, consider the following recommendations: 1. Update the UltimateAI plugin: If an updated version is available, upgrade immediately to the latest version (higher than 2.8.3). 2. Disable the plugin: If an update is not yet available, consider disabling the UltimateAI plugin until a patch is released. 3. Monitor user activity: Implement robust logging and monitoring to detect any suspicious login attempts or unauthorized access. 4. Implement additional authentication measures: Consider using multi-factor authentication (MFA) for admin accounts to add an extra layer of security. 5. Restrict access to the WordPress admin area: Use IP whitelisting or VPN access for administrative functions if possible. 6. Regular security audits: Conduct frequent security assessments of your WordPress installation and all installed plugins. 7. Backup regularly: Ensure you have up-to-date backups of your WordPress site in case of a compromise.
