Critical (9.8) in dlink dir-859 firmware. EPSS 3.7% chance of exploitation in the next 30 days.

D-Link DIR-859 1.05 and 1.06B01 Beta01 devices allow remote attackers to execute arbitrary OS commands via the urn: to the M-SEARCH method in ssdpcgi() in /htdocs/cgibin, because REMOTE_PORT is mishandled.
