A certain Comcast Business Gateway configuration of the SMC SMCD3G-CCR with firmware before 1.4.0.49.2 has a default password of D0nt4g3tme for the mso account, which makes it easier for remote attackers to obtain administrative access via the (1) web interface or (2) TELNET interface.

Multiple cross-site request forgery (CSRF) vulnerabilities in the web interface on the SMC SMCD3G-CCR (aka Comcast Business Gateway) with firmware before 1.4.0.49.2 allow remote attackers to (1) hijack the intranet connectivity of arbitrary users for requests that perform a login via goform/login, or hijack the authentication of administrators for requests that (2) enable external logins via an mso_remote_enable action to goform/RemoteRange or (3) change DNS settings via a manual_dns_enable action to goform/Basic.

The web management portal on the SMC SMCD3G-CCR (aka Comcast Business Gateway) with firmware before 1.4.0.49.2 uses predictable session IDs based on time values, which makes it easier for remote attackers to hijack sessions via a brute-force attack on the userid cookie.
