Ensure sudo visiblepw is configured

How it is checked

Audit method: Shell command

alt0() { command -v grep >/dev/null 2>&1 || { echo "step1: grep not installed"; return 1; }; o=$(bash -c 'grep -rPi -- '"'"'^\h*Defaults\h+([^#]+,\h*)?visiblepw\b'"'"' /etc/sudoers /etc/sudoers.d/' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; }; if alt0; then echo compliant; fi

Expected output

compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Ensure sudo will not prompt for a password on a terminal where it would be displayed. Edit the appropriate sudoers file with visudo and remove any line that enables visiblepw, or explicitly disable it: # visudo Add or correct the line: Defaults !visiblepw
