CVE-2024-43009Network attack vector

Browser script execution via unsanitized Referer reflection

Published Aug 16, 2024 · Updated Aug 19, 2024

Reflected XSS in ZZCMS 2023 and earlier allows remote attackers to execute JavaScript in a victim's browser through a crafted Referer header. The user/login.php response inserts HTTP_REFERER directly into HTML without sanitization, causing header content to be interpreted as markup and script. Exploitation requires a victim to follow a crafted request carrying the header; successful execution can alter displayed content or act within the victim's browser session.
