Vulnerability V-218745

Note: If the server being reviewed is hosting SharePoint, this is Not Applicable. For Request Filtering, the ISSO must document and approve all allowable scripts the website allows (white list) and denies (black list). The white list and black list will be compared to the Request Filtering in IIS 10.0. Request Filtering at the site level take precedence over Request Filtering at the server level. Follow the procedures below for each site hosted on the IIS 10.0 web server: Open the IIS 10.0 Manager. Click the site name to review. Double-click Request Filtering->File Name Extensions Tab. If any script file extensions from the black list are not denied, this is a finding.

Follow the procedures below for each site hosted on the IIS 10.0 web server: Open the IIS 10.0 Manager. Click the site name to review. Double-click Request Filtering->File Name Extensions Tab->Deny File Name Extension. Add any script file extensions listed on the black list that are not listed. Select "Apply" from the "Actions" pane.
