Researchers discovered vulnerabilities that can allow for full site takeover in login and e-commerce add-ons for the popular website-building platform.
Researchers have discovered three WordPress plug-ins with the same vulnerability that allows an attacker to update arbitrary site options on a vulnerable site and completely take it over. Exploiting the flaw does require some action from the site administrator, however.
On Nov. 5, 2021, the Wordfence Threat Intelligence team started a process to disclose a vulnerability researchers had found in “Login/Signup Popup,” a WordPress plug-in installed on more than 20,000 sites, Wordfence’s Chloe Chamberland wrote in a post published online Thursday.
However, a few days later they discovered that the flaw was present in two other plug-ins by the same developer, who goes by the online name of XootiX. They are “Side Cart Woocommerce (Ajax),” which has been installed on more than 60,000 sites, and “Waitlist Woocommerce (Back in stock notifier),” which has been installed on more than 4,000.
