CVE-2018-20219

8.1 HIGH 15% exploit odds No fix listed Auth & access Device

What it is

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.

At a glance

Exploit odds: 14.6% chance of exploitation in the next 30 days (EPSS). Higher than most.
Fix: No patch or advisory is linked yet. Look at mitigations or restrict exposure.
