Vulnerability discussion

The Apache web server can be modified through parameter modification, patch installation, upgrades to the Apache web server or modules, and security parameter changes. With each of these changes, there is the potential for an adverse effect such as a denial of service (DoS), Apache web server instability, or hosted application instability. To limit changes to the Apache web server and limit exposure to any adverse effects from the changes, files such as the Apache web server application files, libraries, and configuration files must have permissions and ownership set properly to only allow privileged users access.

Check content

Obtain a list of the user accounts for the system, noting the privileges for each account. Verify with the System Administrator (SA) or the Information System Security Officer (ISSO) that all privileged accounts are mission essential and documented. Verify with the SA or the ISSO that all non-administrator access to shell scripts and operating system functions are mission essential and documented. If undocumented privileged accounts are found, this is a finding. If undocumented access to shell scripts or operating system functions is present, this is a finding.

Fix text

Ensure non-administrators are not allowed access to the directory tree, the shell, or other operating system functions and utilities.

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.
