CVE-2023-39269Network attack vector

Web-server outage via unthrottled resource allocation

Published Aug 8, 2023 · Updated Aug 12, 2025

Resource exhaustion in Siemens RUGGEDCOM ROS device web servers allows remote attackers to interrupt web access over the network. Siemens identifies unlimited or unthrottled resource allocation in the web server but does not disclose the request type or allocated resource. No authentication or user interaction is required; successful exploitation causes total web-server unavailability, with recovery possible after traffic stops.
