TMA-ESXI9-6.5.11
Host SSH daemon, if enabled, must not permit tunnels
Beschreibung
Preventing tunnel creation in the SSH daemon is a security measure aimed at thwarting unauthorized network tunneling through the host. This control, when enforced, helps mitigate the risks associated with potential data exfiltration or unauthorized network access that could occur via SSH tunnels. The audit reads /etc/ssh/sshd_config and requires PermitTunnel no (unset = OpenSSH default no). Runs in the ESXi Shell (busybox sh) as root.
So wird geprüft
Prüfmethode: Shell-Befehl
f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
v=$(awk 'tolower($1)=="permittunnel" {print tolower($2); exit}' "$f")
case "$v" in '') echo compliant ;; no) echo compliant ;; *) echo "PermitTunnel $v" ;; esac- Erwartete Ausgabe
compliant
So wird behoben
Behebungsmethode: Anleitung oder Infrastruktur-Patch
To remediate this recommendation, set PermitTunnel no, restart SSH if authorized, and verify SSH tunnel devices cannot be created.
