Description
A web server can provide many features, services, and processes. Some of these may be deemed unnecessary or too unsecure to run on a production DOD system. VAMI can be configured to load any number of external modules, but only a specific few are provided and supported by VMware. Additional, unexpected modules must be removed.

ℹ️ Check
At the command prompt, run the following command: # /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf 2>/dev/null\|awk '/server\.modules/,/\)/'\|sed -e 's/^[ ]*//' Expected result: server.modules=( "mod_access", "mod_accesslog", "mod_proxy", "mod_cgi", "mod_rewrite", "mod_magnet", "mod_setenv", #7 ) If the output does not match the expected result, this is a finding. Note: The command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash".

✔️ Fix
Navigate to and open: /opt/vmware/etc/lighttpd/lighttpd.conf Configure the "server.modules" section to the following: server.modules = ( "mod_access", "mod_accesslog", "mod_proxy", "mod_cgi", "mod_rewrite", ) server.modules += ( "mod_magnet" ) Restart the service with the following command: # vmon-cli --restart applmgmt
