Description
CGI and ASP scripts represent one of the most common and exploitable means of compromising a web server. All CGI and ASP program files must be segregated into their own unique folder to simplify the protection of these files. ASP scripts must be placed into a unique folder only containing other ASP scripts. JAVA and other technology-specific scripts must also be placed into their own unique folders. The placement of CGI, ASP, or equivalent scripts to special folders gives the Web Manager or the System Administrator (SA) control over what goes into those folders and to facilitate access control at the folder level.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-218779r1022698_chk)

Determine whether scripts are used on the web server for the target website. Common file extensions include, but are not limited to: .cgi, .pl, .vbs, .class, .c, .php, and .asp. All interactive programs must be placed in unique designated folders based on CGI or ASP script type. For modular and/or third-party applications, it is permissible to have script files in multiple folders. Open the IIS 10.0 Manager. Right-click the IIS 10.0 web site name and select "Explore". Search for the listed script extensions. Each script type must be in its unique designated folder. If scripts are not segregated from web content and in their own unique folders, this is a finding. If the website does not utilize CGI, this finding is Not Applicable.

Fix Text (F-20250r311236_fix)

All interactive programs must be placed in unique designated folders based on CGI or ASP script type. Open the IIS 10.0 Manager. Right-click the IIS 10.0 web server name and select "Explore". Search for the listed script extensions. Move each script type to its unique designated folder. Set the permissions to the scripts folders as follows: Administrators: FULL TrustedInstaller: FULL SYSTEM: FULL ApplicationPoolId:READ Custom Service Account: READ Users: READ ALL APPLICATION PACKAGES: READ
