DescriptionNVD

SDMC NE6037 cable modem routers running firmware 7.1.6.0.25 and 7.1.6.1.9_B9 contain a hardcoded password vulnerability in the web management interface recovery endpoints (mgmt.php, npcmd.php) that allows unauthenticated attackers to gain root access by submitting the hardcoded credential to the recovery endpoint via HTTP. Attackers can leverage this hardcoded password to enable filtered SSH and Telnet services on the device, resulting in unauthenticated root-level remote access to the underlying system.

AnalysisAI

Unauthenticated remote root access on SDMC NE6037 cable modem routers running firmware 7.1.6.0.25 and 7.1.6.1.9_B9 is achievable by submitting a hardcoded credential to recovery endpoints (mgmt.php, npcmd.php) in the web management interface. Attackers can then enable filtered SSH/Telnet services to obtain persistent root-level shell access. …

RemediationAI

Within 24 hours: Scan all networks to identify SDMC NE6037 devices running firmware 7.1.6.0.25 or 7.1.6.1.9_B9; document inventory and network placement. Within 7 days: Restrict access to mgmt.php and npcmd.php endpoints via firewall rules or WAF, disable HTTP/HTTPS management interface where operationally feasible, or limit administrative access to hardened bastion hosts only; implement network segmentation isolating affected devices from critical infrastructure and customer networks. …
