CVE-2021-37208Network attack vector

Sensitive-information disclosure via configuration-page script injection

Published Mar 8, 2022 · Updated Aug 12, 2025

Cross-site scripting in Siemens RUGGEDCOM ROS 4.x before 4.3.8 and 5.x before 5.6.0 allows attackers to retrieve sensitive information. The web server configuration page fails to neutralize special characters before rendering attacker-controlled content. Exploitation requires a privileged position and a victim to open the affected page, where injected script runs in the victim's browser context.
