CVE-2020-20808Public exploitNetwork attack vector

Browser script execution via unencoded search parameters

Published Aug 3, 2023 · Updated Oct 17, 2024

Reflected XSS in Qibosoft Qibosoft 7 and earlier allows remote attackers to execute script in a user's browser through a crafted search URL. The do/search.php handler reflects the eindtijd and starttijd query parameters without neutralizing injected SVG event-handler markup. No authentication is required, but a victim must open the crafted URL; exploitation runs attacker-supplied script in the site's browser context.
