CVE-2025-32472Network attack vector

Web interface DoS via Slowloris connection exhaustion

Published Apr 28, 2025 · Updated Apr 28, 2025

Uncontrolled resource consumption in SICK multiScan100 and picoScan100 all firmware versions allows remote attackers to hang the web interface. The embedded web server retains deliberately slow, incomplete HTTP connections long enough to exhaust request-handling capacity. No authentication or user interaction is required; sustained network access makes the device web page unresponsive, with no other impact reported.
