-- Description --
This stored XSS vulnerability allows any logged in user
to inject malicious code in the comments section:
e.g. "><body onLoad=confirm("XSS")>
The vulnerability exists because the user input is not properly sanitized
and this can lead to malicious code injection that will be executed on the
target?s browser
-- Proof of Concept --
1. The attacker posts a new comment which contains our payload:
"><body onLoad=confirm("XSS")>
2. The stored XSS can be triggered when any user visits the link of the
uploaded content
-- Solution --
The vendor has fixed the issue in the version 4.21
