A Critical Security Vulnerability in All-in-One WP Migration Exposed

Seattle | September 11, 2023 – All-in-One WP Migration, a widely utilized plugin for WordPress websites, has recently come under scrutiny due to a significant security flaw. This vulnerability has the potential to compromise the security of affected websites, allowing unauthorized access token manipulation. Essentially, this means that attackers could exploit this vulnerability to gain access to sensitive information. The flaw is specifically found in the premium extensions provided by ServMask, the plugin’s vendor. These premium extensions, which include Box, Google Drive, One Drive, and Dropbox, were designed to facilitate data migration via third-party platforms. However, the flaw tracked as CVE-2023-40004, could result in a severe data breach, exposing user details, crucial website data, and proprietary information.

The security breach was initially uncovered on July 18, 2023, by Rafie Muhammad, a researcher associated with PatchStack. Muhammad promptly reported the issue to ServMask, which took swift action to address the vulnerability. ServMask released security updates on July 26, 2023, which incorporated permission and nonce validation into the affected extensions’ initialization functions.

To safeguard their websites, users of the impacted premium third-party extensions are strongly encouraged to upgrade to the following fixed versions:

1. Box Extension: v1.54
2. Google Drive Extension: v2.80
3. OneDrive Extension: v1.67
4. Dropbox Extension: v3.76

Additionally, it is advisable for users to update their base plugin, All-in-One WP Migration, to the latest version, v7.78, which is available free of charge.

Although it is worth noting that the vulnerability is somewhat mitigated by the fact that the All-in-One WP Migration plugin is typically active only during site migration projects, it is crucial for affected users to act promptly and update their plugins. This proactive measure will help ensure the security and integrity of their websites.
