CVE-2024-24837 is a Cross-Site Request Forgery (CSRF) vulnerability affecting multiple WordPress migration plugins developed by Frédéric GILLES, specifically FG PrestaShop to WooCommerce, FG Drupal to WordPress, and FG Joomla to WordPress. These plugins facilitate data migration from PrestaShop, Drupal, and Joomla platforms to WooCommerce or WordPress, respectively. The vulnerability exists in versions up to 4.44.3 for FG PrestaShop to WooCommerce, 3.67.0 for FG Drupal to WordPress, and 4.15.0 for FG Joomla to WordPress. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, an attacker could craft malicious web requests that, when executed by an authenticated administrator or user with sufficient privileges, could trigger unauthorized migration operations or configuration changes without the user's consent. The lack of proper anti-CSRF tokens or validation mechanisms in these plugins enables this attack vector. Although no known exploits are currently reported in the wild, the vulnerability's presence in widely used migration plugins poses a risk, especially during migration or maintenance windows when administrative users are active. The vulnerability impacts the integrity and potentially availability of the migration process, as unauthorized actions could corrupt or disrupt data migration workflows. Since these plugins operate within WordPress environments, the attack surface includes any WordPress site using these plugins for migration purposes. The vulnerability does not require user interaction beyond the victim visiting a malicious page while authenticated, and no authentication bypass is involved; the attacker relies on the victim's authenticated session. No patch links are currently provided, indicating that users must monitor vendor updates closely.

For European organizations, this vulnerability could lead to unauthorized manipulation of migration processes between e-commerce and CMS platforms, potentially resulting in data corruption, loss of data integrity, or disruption of business operations during critical migration phases. Organizations relying on these plugins to migrate or synchronize data between PrestaShop, Drupal, Joomla, and WooCommerce/WordPress could face operational downtime or data inconsistencies if attackers exploit this vulnerability. Given the importance of e-commerce and content management systems in European digital business infrastructure, exploitation could affect customer trust, lead to compliance issues (especially under GDPR if personal data is mishandled), and cause financial losses. The impact is particularly significant for organizations with frequent migration activities or those that maintain these plugins active in production environments. However, since exploitation requires an authenticated user session, the threat is mitigated somewhat by internal access controls and user privilege management. Nevertheless, phishing or social engineering attacks could be used to lure administrators to malicious sites, increasing risk.

1. Immediate mitigation involves disabling or uninstalling the affected plugins if migration is not actively required. 2. Restrict administrative access to trusted networks and enforce multi-factor authentication (MFA) to reduce the risk of session hijacking or unauthorized access. 3. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious POST requests that could indicate CSRF attempts targeting these plugins. 4. Educate administrators and users with elevated privileges about the risks of CSRF and the importance of avoiding clicking on untrusted links or visiting unknown websites while logged into administrative accounts. 5. Monitor plugin vendor channels closely for security patches or updates addressing this vulnerability and apply them promptly once available. 6. Review and harden WordPress security configurations, including ensuring that nonces or CSRF tokens are properly implemented in custom or third-party plugins. 7. Conduct regular security audits and penetration testing focusing on administrative interfaces and migration workflows to detect potential CSRF or related vulnerabilities. 8. Limit plugin usage to staging or migration environments rather than production where possible, to reduce exposure.
