A critical vulnerability has been identified in the popular UpdraftPlus: WP Backup & Migration Plugin, potentially impacting over 3 million WordPress websites. This security flaw allows unauthenticated attackers to exploit a PHP Object Injection vulnerability through deserialization of untrusted input. The issue affects all versions of the plugin up to and including 1.24.11, but a patch has been released in version 1.24.12 to address this significant risk.
The vulnerability, officially documented as CVE-2024-10957, has a CVSS score of 8.8, categorizing it as a high-risk issue. It emerged from the recursive_unserialized_replace function within the plugin’s code, which allows attackers to inject PHP Objects, compromising the security of websites utilizing the plugin. While no known Proof of Concept (PoC) chains have been reported within the vulnerable software itself, the risk escalates if an additional plugin or theme also contains a vulnerability.
According to researcher Webbernaut in the Wordfence report, exploiting this vulnerability requires an administrator to perform a search and replace action, triggering the exploit. The consequences of this exploit could include unauthorized file deletions, retrieval of sensitive user data, and even remote code execution. This highlights the importance of regular updates and vigilance in maintaining WordPress installations.
Website owners using the UpdraftPlus plugin are strongly advised to take immediate action to mitigate this vulnerability by updating to version 1.24.12 or any subsequent patched version. Updating plugins through the WordPress dashboard can significantly reduce the window of exposure to potential attacks. Administrators should review their WordPress installations, including all active plugins, for any vulnerabilities and ensure that all software components are up to date to maintain a secure online presence.
As cyber threats evolve, staying informed about vulnerabilities like CVE-2024-10957 is crucial. Acting promptly to apply necessary updates can prevent significant security breaches. It is essential for website owners to stay vigilant and proactive in addressing vulnerabilities to protect their online assets.
In conclusion, the identification of this critical vulnerability in the UpdraftPlus plugin underscores the ongoing importance of cybersecurity measures in the digital landscape.
