  • Vulnerability in Easy Forms for MailChimp 6.1.2 and older

    Panagiotis Vagenas, a Wordfence Security Researcher, has discovered a reflected cross site scripting vulnerability in the Easy Forms for MailChimp plugin for WordPress. There are over 40,000 active installations according to wordpress.org. We shared the details of the vulnerability with the author on Monday and they released version 6.1.3 on Tuesday, which includes a fix for the vulnerability.

    An attack leveraging this reflected cross site scripting vulnerability would require an admin to click on a link which might be accomplished via some kind of social engineering attack. Accomplishing that could enable an attacker to perform a number of administrative functions, including adding a user with admin privileges, effectively giving them full control of the website. It is important to note that many modern browsers, such as Chrome and Safari, protect against these types of scripts running on the client side, which diminishes the odds that this vulnerability will be exploited in the wild.

    CVSS Severity: 8.8 (High)

    What to do
    Both Premium and free Wordfence users with the firewall enabled are already protected. Anyone not running Wordfence should upgrade to version 6.1.3 immediately.

  • Vulnerability Roundup for Thursday July 28th

    Vulnerability Roundup for Thursday July 28th

    This is a roundup of recent vulnerabilities in WordPress plugins that you should be aware of.

    This morning we published details of a reflected cross site scripting vulnerability in Easy Forms for MailChimp versions 6.1.2 and older. One of our own researchers discovered this vulnerability and notified the author who released a fix Tuesday. Upgrade immediately if you run this plugin.

    The following notable plugins have had vulnerabilities reported in the past week. If you use any of these plugins, upgrade promptly:

    Form Lightbox Plugin ScreenshotThe Form Lightbox plugin has been removed from the WordPress repository. However it contains a vulnerability that allows an attacker to update any option in the WP database, thereby gaining admin access to a site. If you use this plugin we recommend that you remove it.

    The most recent version of this plugin was version 2.1 and it had approximately 34,000 downloads at the time of it’s removal. The slug for the plugin is form-lightbox.

    Improved vulnerability alerting in Wordfence

    Note that since the 6.1.11 update of Wordfence, when you are now alerted about a plugin update, if that plugin has a known vulnerability it will be a ‘critical’ alert and if it does not have a known vulnerability the alert will be a ‘warning’. This allows you to easily differentiate between urgent plugin updates and routine.

    Summer of Pwnage

    In the past month the Dutch community project the Summer of Pwnage has uncovered multiple WordPress vulnerabilities. We encourage you to run your eye down this advisories page from the project and update any of the plugins that you run that may be affected.

    We encourage you to share these vulnerabilities with the larger WordPress community to help keep site owners safe from exploitation.

  • New Vulnerability in All in One SEO Pack Plugin 2.3.7 and earlier

    Yesterday morning Panagiotis Vagenas, a Wordfence Security Researcher, discovered a new vulnerability in the All in One SEO Pack WordPress plugin. This is in addition to another serious vulnerability we wrote about yesterday morning in the same plugin.

    As detailed yesterday, All in One SEO Pack is an extremely popular plugin with over 1,000,000 active installs. Both free and Premium Wordfence users with the firewall enabled had partial protection at the time we discovered this new vulnerability. A firewall rule that provides complete protection was added to the Threat Defense Feed yesterday morning.

    The author released version 2.3.8 which fixes the vulnerability yesterday afternoon.

    This unauthenticated stored XSS vulnerability allows an attacker to inject javascript code into a page that requires admin privileges to view. When a site admin visits the page, the malicious code that runs can perform administrative actions such as modifying existing user privileges, creating a new admin user or stealing admin session tokens.

    This exploit only works if the user has enabled the sitemap module in the plugin. We have no way of estimating the percentage of All in One SEO Pack users who are vulnerable, but given the widespread use of the plugin and the importance of sitemaps for SEO, it is likely that 100s of thousands of sites are impacted.

    CVSS Severity: 8.8 (High)

    What to do

    Premium Wordfence customers that have the firewall enabled are already completely protected by the firewall rule we added yesterday morning. Free Wordfence users running the All in One SEO Pack plugin should upgrade to version 2.3.8 immediately, and will receive a rule to completely protect against this vulnerability on August 11th.

    In addition we encourage you to share this post with the broader WordPress community to create awareness of this serious security issue.
