Three Plugins Backdoored in Supply Chain Attack

This entry was posted in Research, WordPress Security on December 27, 2017 by Dan Moen   54 Replies

In the last two weeks, the WordPress.org repository has closed three plugins because they contained content-injection backdoors. "Closing" a plugin means that it is no longer available for download from the repository, and will not show up in WordPress.org search results. Each of them had been purchased in the previous six months as part of the same supply chain attack, with the goal of injecting SEO spam into the sites running the plugins....read more

This entry was posted in Vulnerabilities, Wordfence, WordPress Security on December 13, 2017 by Dan Moen   49 Replies

The Wordfence team regularly discovers security issues with commercial services, such as WordPress hosting providers, that put their users at risk. In some cases, the issue is quite severe, putting thousands of websites at risk simultaneously. In these instances, our standard approach has been to contact the service provider directly, provide them with the details and work with them toward resolution. Lately these issues have become more common, so we've decided to formalize our approach going forward, updating our Vulnerability Disclosure Policy to specifically address these scenarios....read more

Postman SMTP Plugin With Unpatched Vulnerability Removed From Directory

This entry was posted in Vulnerabilities, Wordfence, WordPress Security on October 6, 2017 by Dan Moen   24 Replies

We have received a number of questions regarding the Postman SMTP plugin which was removed from the WordPress.org directory this week. According to an archived snapshot, the plugin is installed on over 100,000 websites. We assume it was removed because it contains a publicly known reflected cross-site scripting (XSS) vulnerability that has not been fixed. Both Wordfence Free and Premium users who have the firewall enabled have been protected against attempts to exploit this vulnerability from day one. In addition, we alerted all Wordfence users who have the plugin installed when it was removed from the plugin directory....read more
