CVE-2024-47002Public exploitNetwork attack vector

Authenticated HTML injection via unescaped VLAN identifier

Published Jan 15, 2025 · Updated Jan 15, 2025

HTML injection in Observium CE 24.4.13528 allows remote authenticated users to inject arbitrary markup via a crafted VLAN request. The html/pages/vlan.inc.php page inserts the vlan_id parameter directly into a VLAN heading without HTML encoding. Exploitation requires a logged-in user to follow a malicious link, causing attacker-supplied markup to load in that user's browser.
