Linux assessment fails if escape sequences are found in /etc/issue

Problem

When running a CIS-CAT Pro Assessor scan against a Linux target system that includes escape sequences in the /etc/issue file, the assessment halts with the following error:

These sequences are occasionally used in combination with color or other character formatting.

You can use the file /etc/issue command to verify whether this is the case:

Solution

Temporarily replace or remove any occurrence of the escape character sequence in the /etc/issue file before initiating the assessment. The contents can then be restored after the scan completes.
