CVE-2025-48733Network attack vector

Unauthenticated device reboot via unprotected function

Published Jul 22, 2025 · Updated Jul 23, 2025

Missing authentication in DuraComm SPM-500 DP-10iN-100-MU 4.10 and earlier allows remote attackers to repeatedly reboot the device. CISA identifies an access-control omission in a reboot-capable function but does not publish the request path, handler, or protocol operation that invokes it. Network reachability alone is sufficient; no credentials or user interaction are required, and repeated requests interrupt device availability.
