Wordfence has highlighted another vulnerable WordPress plugin that boasts more than 1 million active installations.

As revealed in their blog post, the popular WordPress plugin Page Builder by SiteOrigin had multiple security bugs. Exploiting these bugs could allow an adversary to gain complete control of the target website.

Briefly, both the researchers found two CSRF to Reflected XSS vulnerabilities. They deemed both the bugs as high-severity flaws, each receiving a CVSS score of 8.8.

The first of these bugs existed in the plugin’s live editor feature. Whereas, the other affected the action_builder_content function linked with AJAX action wp_ajax_so_panels_builder_content.

As described by the researchers,

Both of these flaws allow attackers to forge requests on behalf of a site administrator and execute malicious code in the administrator’s browser. The attacker needs to trick a site administrator into executing an action, like clicking a link or an attachment, for the attack to succeed.

Eventually, an attacker could either create new admin accounts on the site, redirect site admin, or inject backdoor.

The following video demonstrates the PoC of the exploit.

Patches Available – Update Now!

After discovering the vulnerabilities, Wordfence swiftly reached out to the developers to report the flaws.

Consequently, the developers acknowledged the bugs the very next day and also released patches for both bugs.

Hence, now, the users can update their websites with the latest Page Builder by SiteOrigin plugin version 2.10.16 that contains the fixes. Since the PoC is out, users must ensure updating their sites very quickly to stay protected.

Recently, the researchers also highlighted bugs in two related WordPress plugins that posed a threat to over a million websites.

Analytics

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
