Description
The Options directive configures the web server features that are available in particular directories. The IncludesNOEXEC feature controls the ability of the server to utilize SSIs while disabling the exec command, which is used to execute external scripts. If the full includes feature is used it could allow the execution of malware leading to a system compromise.
