TMA-F5-BIGIP-3.3
Ensure access to Configuration utility is restricted to needed IP addresses only
Description
It is recommended to maintain secure access to the GUI by allowing only trusted IP addresses or range of IP addresses PASS requires sys httpd allow to be a list of addresses (not All). Audited against tmsh output with defaults shown: save the concatenated output of 'tmsh list auth password-policy all-properties', 'tmsh list auth source all-properties', 'tmsh list auth remote-user all-properties', 'tmsh list auth radius all-properties', 'tmsh list sys httpd all-properties', 'tmsh list sys sshd all-properties', 'tmsh list sys global-settings all-properties', 'tmsh list cli global-settings all-properties', 'tmsh list sys ntp', 'tmsh list sys snmp all-properties', 'tmsh list sys syslog' and 'tmsh list net self all-properties'. Patterns are scoped to the named top-level block.
How it is checked
Audit method: Configuration pattern
- Pattern
(?m)^sys httpd \{\n(?:[ \t]+[^\n]*\n)*?[ \t]+allow \{ (?:[0-9a-fA-F.:/\-]+ )+\}[ \t]*$
How it is fixed
Fix method: Guidance or infrastructure patch
tmsh modify sys httpd allow replace-all-with { 10.0.0.0/255.255.255.0 } tmsh save sys config # CIS guidance: If the output of the above command show ALL, the following command would be executed to modify the settings: modify modify /sys httpd allow replace-all-with { <IP address or IP address }
