CVE-2023-2667Public exploitNetwork attack vector

Authenticated script execution via reflected page parameter

Published May 12, 2023 · Updated Aug 2, 2024

Reflected XSS in SourceCodester Lost and Found Information System 1.0 allows remote authenticated users to execute scripts via the page parameter. The admin index route reflects the page query parameter into HTML without neutralizing tag and event-handler syntax, so a crafted image element executes its onerror handler. A management-site session and a victim who follows the crafted request are required; successful exploitation runs attacker-controlled script in the victim's browser.
