CVE-2018-10996
The weblogin_log function in /htdocs/cgibin on D-Link DIR-629-B1 devices allows attackers to execute arbitrary code or cause a denial of service (buffer overflow) via a session.cgi?ACTION=logout request involving a long REMOTE_ADDR environment variable.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
