SV-36309r2_rule MIME types for csh or sh shell programs must be disabled.

Vulnerability discussion

Users must not be allowed to access the shell programs. Shell programs might execute shell escapes and could then perform unauthorized activities that could damage the security posture of the web server. A shell is a program that serves as the basic interface between the user and the operating system. In this regard, there are shells that are security risks in the context of a web server and shells that are unauthorized in the context of the Security Features User's Guide.

Check content

Enter the following commands: grep "Action" /usr/local/apache2/conf/httpd.conf grep "AddHandler" /usr/local/apache2/conf/httpd.conf If either of these exist and they configure /bin/csh, or any other shell as a viewer for documents, this is a finding.

Fix text

Disable MIME types for csh or sh shell programs.

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.
