CVE-2018-20219: 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. After successful authentication, the device sends an authentication cookie to the end user such that they can access the devices web administration panel. This token is hard-coded to a string in the source code (/usr/share/www/check.lp file). By setting this cookie in a browser, an attacker is able to maintain access to every ENC-400 device without knowing the password, which results in authentication bypass. Even if a user changes the password on the device, this token is static and unchanged.

Security readout for executives and security teams

Teracue ENC-400 devices running firmware 2.56 and below use a fixed web authentication cookie. Anyone who obtains or knows that static token could keep administrative web access without the device password, and changing the password does not invalidate the token. Exposure is limited to Teracue ENC-400 devices on firmware 2.56 or below, especially where the web administration panel is reachable from untrusted networks. The source bundle does not identify other Teracue products or fixed versions. Prioritize remediation for any exposed ENC-400 encoder. This is not a broad enterprise software issue, but affected devices may be difficult to secure if the management interface is reachable and no vendor fix is available. Mitigation focus: Identify all Teracue ENC-400 devices and their firmware versions.; Check Teracue or reseller guidance for fixed firmware or replacement advice.; Remove web administration from internet or untrusted network exposure..
