Technical description

Admidio 4.0.12 through 4.3.17 and 5.0.0 before 5.0.15 contains a reflected cross-site scripting vulnerability in system/redirect.php that allows unauthenticated attackers to inject JavaScript via the url GET parameter, due to an incomplete fix for CVE-2021-43810. Attackers can craft a javascript: URL containing a decoy http:// segment that passes validation and executes script in the Admidio origin when victims click the redirect link.
