A hugely popular plugin for the WordPress website builder was carrying a high-severity flaw that could have allowed threat actors to take full control of the target website, experts have found.
Cybersecurity researchers from PatchStack discovered a flaw in the āEssential Addons for Elementorā plugin - a library for the Elementor page builder, consisting of 90 different extensions.
The team claims more than a million WordPress sites have the library installed.

The flaw, which has since been patched, is being tracked as CVE-2023-32243, and itās described as an unauthenticated privilege escalation flaw on the password reset functionality. All versions from 5.4.0 up to 5.7.1 are vulnerable, the researchers are saying. Apparently, a threat actor could, with relative ease, reset the password of an admin account, assume control, and thus take over the entire website.
āIt is possible to reset the password of any user as long as we know their username, thus being able to reset the password of the administrator and login on their account," PatchStack said. āThis vulnerability occurs because this password reset function does not validate a password reset key and instead directly changes the password of the given user.ā

When a malicious actor takes control of a website, there are a number of things they could do, from stealing sensitive information and engaging in identity theft, to distributing malware and engaging in ad fraud.
Prior to exploiting the flaw, the attackers need to know a couple of things, including the username of the systemās admin. They also need to set a random value in POST āpage_idā and āwidget_idā inputs, as otherwise, the plugin would report an error to the actual admin. Furthermore, thes must provide the correct nonce value on the āeael-resetpassword-nonceā as that validates the password reset and sets a new password on the āeael-pass1ā and āeael-pass2ā parameters.
If youāre using Essential Addons for Elementor, make sure to bring it up to version 5.7.2.
