CVE-2017-18046
Buffer overflow on Dasan GPON ONT WiFi Router H640X 12.02-01121 2.77p1-1124 and 3.03p2-1146 devices allows remote attackers to execute arbitrary code via a long POST request to the login_action function in /cgi-bin/login_action.cgi (aka cgipage.cgi).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
