CVE-2024-30921Public exploitNetwork attack vector

Browser script execution via unsanitized debug text

Published Apr 18, 2024 · Updated Nov 4, 2025

Reflected XSS in DerbyNet 9.0 and earlier allows remote attackers to execute JavaScript through a crafted photo.php URL path. photo.php displays debug text derived from the user-controlled path without adequate HTML sanitization, causing injected markup and event handlers to run in the browser. The disclosure reports no authentication requirement, while CISA scores the attack as low privilege; a victim must follow the crafted URL, exposing browser-session data and actions.
