CVE-2023-1743Public exploitNetwork attack vector

Browser script execution via unescaped page parameter

Published Mar 30, 2023 · Updated Aug 2, 2024

Cross-site scripting in SourceCodester Grade Point Average Calculator 1.0 allows remote authenticated users to execute script through index.php. The index.php routing logic places the page query value into an HTML response without neutralizing script-capable characters. Exploitation requires low-privileged access and a victim to open a crafted URL; script execution is confined to the victim's browser context.
