CVE-2024-38308

Stored XSS via unescaped HTTP request logs

Published Sep 27, 2024 · Updated Sep 27, 2024

Stored cross-site scripting in Advantech ADAM-5550 all versions allows adjacent remote attackers to execute script in its web interface. The logs page records received HTTP requests and emits their attacker-controlled content into page output without neutralizing executable markup. Opening the logs page triggers the stored payload in its origin, enabling access to or modification of data available to that browser session.
