CVE-2024-52415 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the skipstorm SK WP Settings Backup plugin for WordPress, affecting all versions up to 1.0. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, potentially causing unauthorized actions. In this case, the CSRF flaw is coupled with an object injection vulnerability, which can enable attackers to inject malicious serialized objects into the application’s processing flow. This combination can lead to severe consequences such as arbitrary code execution, data manipulation, or corruption of backup settings. The plugin’s purpose is to backup and restore WordPress settings, making it a critical component for site configuration management. The vulnerability arises because the plugin does not properly verify the origin of requests or sanitize input before deserializing objects, allowing attackers to craft malicious requests that execute in the context of an authenticated administrator. Although no public exploits have been reported yet, the presence of object injection significantly raises the risk profile. The vulnerability was published on November 16, 2024, and no CVSS score has been assigned. The lack of patches or mitigations from the vendor at this time increases the urgency for administrators to take protective measures.

The impact of CVE-2024-52415 can be substantial for organizations using the SK WP Settings Backup plugin. Successful exploitation could allow attackers to alter backup configurations, inject malicious payloads, or execute arbitrary code within the WordPress environment. This compromises the confidentiality, integrity, and availability of the affected websites. Attackers could potentially gain persistent access, disrupt site operations, or use the compromised site as a foothold for further attacks. Since the vulnerability exploits CSRF, it requires an authenticated user session, typically an administrator, which means social engineering or phishing could be used to lure victims into triggering the exploit. The scope is limited to sites using this specific plugin, but given WordPress’s widespread use, the number of affected sites could be significant. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the potential severity. Organizations relying on this plugin for backup and recovery are at risk of losing control over critical configuration data, impacting business continuity and security posture.

To mitigate CVE-2024-52415, organizations should immediately assess their WordPress installations for the presence of the SK WP Settings Backup plugin and disable or uninstall it if possible until a vendor patch is released. Implementing Web Application Firewall (WAF) rules to block suspicious POST requests targeting the plugin’s endpoints can reduce exposure. Administrators should enforce strict CSRF protections site-wide, including the use of nonce tokens and verifying the origin of requests. Regularly monitoring logs for unusual activity related to backup operations or plugin usage is recommended. Limiting administrative access and educating users about phishing and social engineering risks can reduce the likelihood of exploitation. Backup critical data independently of the plugin to ensure recovery options if compromise occurs. Stay informed about vendor updates and apply patches promptly once available. Consider alternative, well-maintained backup plugins with strong security track records as a replacement.
