The White Label CMS plugin for WordPress is an extension that allows website owners to rebrand and customize the WordPress dashboard as well as add their own logos, colors, and other branding elements to reinforce their corporate or personal identity. This plugin offers a convenient way to personalize the user experience and make the website look more professional and unique. By using this tool, website owners can manage their website interface as per specific branding needs, without interfering with the website's functionality and core features.
Recently, a vulnerability has been discovered in the White Label CMS plugin that can potentially compromise the security of the website. Dubbed CVE-2022-0422, this vulnerability affects versions of White Label CMS plugin before 2.2.9. The issue arises due to the plugin's failure to sanitize and validate the wlcms[_login_custom_js] parameter before reflecting it back in the response while previewing, leading to a Reflected Cross-Site Scripting (XSS) issue. An attacker can manipulate the input values of the parameter and inject malicious scripts that will execute in the context of the victim's browser. This could allow the attacker to steal sensitive information, login credentials, and perform unauthorized actions on the website.
The CVE-2022-0422 vulnerability, if exploited, can lead to disastrous consequences for website owners. Attackers can utilize this vulnerability to execute malicious scripts in the victim's web browser and gain access to sensitive information, including personal data, login credentials, and payment details. They could also use the vulnerability to execute arbitrary commands, make unauthorized transactions, and take over the website's administrative privileges. As a result, the website owner would lose control over their website and leave their digital assets vulnerable to further attacks.
