CVE-2024-11293 is an authentication bypass vulnerability classified under CWE-287, found in the Pie Register - Social Sites Login add-on for WordPress developed by Genetech Solutions. This plugin facilitates user registration and login via social media tokens. The vulnerability exists because the plugin does not adequately verify the identity of the user returned by the social login token. Specifically, if an attacker knows the email address of a target user and the target user does not have an existing account linked to the social login provider, the attacker can exploit this flaw to bypass authentication and log in as that user, including high-privilege accounts such as administrators. The vulnerability affects all versions up to and including 1.7.9. The attack vector is remote and does not require prior authentication or user interaction, but it has a high attack complexity due to the need to manipulate or obtain valid social login tokens. The impact includes full compromise of confidentiality, integrity, and availability of the affected WordPress site, as attackers can gain unauthorized administrative access. No patches were linked at the time of publication, and no known exploits have been reported in the wild. The vulnerability was published on December 4, 2024, with a CVSS 3.1 base score of 8.1, reflecting high severity with network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.

The impact of CVE-2024-11293 is significant for organizations using the Pie Register - Social Sites Login add-on on WordPress. Successful exploitation allows attackers to bypass authentication controls and assume the identity of any user, including administrators, leading to full site compromise. This can result in unauthorized data access, modification, deletion, and potential site defacement or malware deployment. The integrity and availability of the website are at risk, potentially disrupting business operations and damaging organizational reputation. Since WordPress powers a large portion of the web, and social login plugins are common for user convenience, the scope of affected systems is broad. Attackers do not require prior authentication or user interaction, increasing the risk of automated or targeted attacks. Organizations with sensitive data or critical web services hosted on WordPress are particularly vulnerable, and the breach could cascade into further network compromise if the site is used as a pivot point.

To mitigate CVE-2024-11293, organizations should immediately update the Pie Register - Social Sites Login add-on to a patched version once available. Until a patch is released, consider disabling the social login functionality or the plugin entirely to prevent exploitation. Implement additional verification layers for social login tokens, such as server-side validation against the social provider's API to confirm user identity and token integrity. Restrict administrative access to trusted IP addresses and enforce multi-factor authentication (MFA) for all privileged accounts to reduce the impact of potential account compromise. Regularly audit user accounts and login logs for suspicious activity. Employ web application firewalls (WAFs) with custom rules to detect and block anomalous login attempts related to this vulnerability. Educate site administrators about the risk and ensure timely application of security updates. Finally, monitor threat intelligence sources for any emerging exploits targeting this vulnerability.
