Los Angeles | September 11, 2023 – Recently, a disconcerting security vulnerability has surfaced within the extensively employed All in One WP Migration WordPress Plugin. This revelation has the potential to expose innumerable WordPress websites to the hazard of unauthorized access token manipulation.
The All-in-One WP Migration plugin, renowned for its exquisite proficiency in facilitating seamless migrations of WordPress websites, commands a formidable user base, boasting over 60 million installations. This remarkably versatile plugin offers an assortment of premium extensions, encompassing integrations with distinguished services such as Box, Google Drive, OneDrive, and Dropbox. This, in turn, streamlines the process of transferring content to diverse third-party platforms with utmost ease.
This security vulnerability, known as CVE-2023-40004, allows unauthorized individuals to gain access to and alter token settings in extensions that are affected by it. As a result, it creates an opportunity for malicious actors to steal website migration data, transferring it to their own third-party cloud service accounts or, even more concerning, utilizing it to reinstate harmful backups. When successfully taken advantage of, CVE-2023-40004 can result in the disclosure of extremely sensitive information, including user profiles, essential website data, and proprietary content.
By leveraging this specific weakness, malevolent entities can tamper with the configurations of access tokens associated with the affected extensions. This illicit access effectively swings wide open the gateway to potential exposure of confidential data during the migration process. Consequently, it bestows upon wrongdoers the capability to infiltrate controlled third-party accounts or, in a worst-case scenario, restore nefarious backups.
The proficient security research team at PatchStack, under the sagacious leadership of Rafie Muhammad, has meticulously unveiled this vulnerability ensconced within the initiation function of the afflicted extensions. The origin of this flaw can be traced to the insufficient permission and nonce validation processes, ultimately resulting in an exploitable vulnerability that permits unauthorized users to manipulate access tokens. Remarkably, this vulnerability can be triggered through the WordPress admin_init hook.
In response to this urgent security issue, PatchStack fervently advocates for the proactive implementation of robust permission and nonce validation procedures by plugin and theme developers. This prudent course of action serves as an indispensable bastion against unauthorized access and the clandestine manipulation of confidential information.
