Vulnerability discussion

Remote access to the web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions. A web server can be accessed remotely and must be capable of restricting access from what the DoD defines as nonsecure zones. Nonsecure zones are defined as any IP, subnet, or region that is defined as a threat to the organization. The nonsecure zones must be defined for public web servers logically located in a DMZ, as well as private web servers with perimeter protection devices. By restricting access from nonsecure zones, through internal web server access list, the web server can stop or slow denial of service (DoS) attacks on the web server.As the web server for the vRA Virtual Appliance Management Interface (vAMI), Lighttpd is the primary remote access management system for vRA. Lighttpd must be configured to restrict inbound connections from nonsecure zones. To accomplish this, the SSL engine must be enabled. The SSL engine forces Lighttpd to only listen via secure protocols.

Check content

At the command prompt, execute the following command: grep -A 4 'remoteip' /opt/vmware/etc/lighttpd/lighttpd.conf If the command does not return any output, this is a finding. Note: The output should look like the following: $HTTP["remoteip"] !~ "a.a.a.a" { url.access-deny = ( "" ) } Where a.a.a.a is an allowed IP address.

Fix text

Determine the IP addresses which will be allowed to access Lighttpd. Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf Configure the "lighttpd.conf" file with the following: $HTTP["remoteip"] !~ "a.a.a.a" { url.access-deny = ( "" ) } Note: a.a.a.a is the IPv4 address provided by the ISSO. If additional IPv4 addresses are allowed, use the information shown below instead (3 addresses shown): $HTTP["remoteip"] !~ "a.a.a.a|b.b.b.b|c.c.c.c" { url.access-deny = ( "" ) }

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
