XSS in WordPress Elementor Plugin 2.8.4

January 29, 2020

Overview :

The Elementor plugin before 2.8.5 for WordPress suffers from a reflected XSS vulnerability on the elementor-system-info page. These can be exploited by targeting an authenticated user.

Affected Product(s) :

WordPress Elementor Plugin 2.8.5

Vulnerability Details :

CVE ID :	CVE-2020-8426
	The plugin seems to be very well implemented but there is always a sneaky XSS somewhere. So in comes Burp Suite’s intruder dropping a whole heap of payloads into every dynamic part of the application.

Solution :

Whilst this XSS was not a particularly difficult one to find, it had some nuances that made it awkward to find the right working payload. Persistence and a couple of hours free time were enough to get this working nicely.

The developers of Elementor were contacted prior to this post to ensure they had adequate time to remediate the issue. This has now been fixed with some extra sanitization.
