Open redirect and XSS via unvalidated MFA input
Published May 30, 2023 · Updated Jan 10, 2025
Open redirect and XSS in Joomla! CMS 4.2.0 through 4.3.1 allow remote attackers to redirect or run script via the MFA selection screen. The MFA selection screen accepts input without sufficient validation, but Joomla! has not published the affected parameter, function, or rendering path. Exploitation requires user interaction with attacker-controlled input and can redirect the browser or execute script in the site context.
