CVE-2018-20218: An issue was discovered on Teracue ENC-400 devices with firmware 2.56 and below.

An issue was discovered on Teracue ENC-400 devices with firmware 2.56 and below. The login form passes user input directly to a shell command without any kind of escaping or validation in /usr/share/www/check.lp file. An attacker is able to perform command injection using the "password" parameter in the login form.

Security readout for executives and security teams

CVE-2018-20218 affects Teracue ENC-400 devices running firmware 2.56 and below. The login page can pass the password field into a shell command without proper validation, so a reachable device could allow command execution. Business urgency depends mainly on whether these encoders are exposed to untrusted networks. Exposure is most likely where Teracue ENC-400 web login interfaces are reachable from the internet, partner networks, or broad internal networks. Devices isolated to restricted management networks have lower practical exposure, but still need review if running firmware 2.56 or below. Prioritize this for any internet-exposed or broadly reachable ENC-400 device. Command injection on an appliance login path can lead to device compromise, but urgency should be driven by confirmed asset presence and network exposure. Mitigation focus: Inventory Teracue ENC-400 devices and identify firmware versions.; Restrict web login access to trusted management networks or VPN only.; Check Teracue or maintainer guidance for fixed firmware or vendor mitigations..
