CVE-2024-12845Public exploitNetwork attack vector

Authenticated script execution via unencoded error messages

Published Dec 20, 2024 · Updated Dec 27, 2024

Reflected XSS in emlog Pro 2.4.0 through 2.4.1 allows remote authenticated users to execute script in another user's browser. The $msg path in /include/lib/common.php returns database error text containing attacker-controlled fields without HTML encoding. Exploitation requires a logged-in browser to submit a crafted request, and the resulting script executes within that browser's emlog origin.
