Vulnerability discussion

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

Check content

At the command prompt, execute the following commands: ls -alR /etc/vcac /usr/lib/vcac/server/webapps | grep -E '^-' | awk '$1 !~ /---$/ {print}' If the command produces any output, this is a finding.

Fix text

Remove all world permissions from any listed file with the following command: chmod -R o-rwx /etc/vcac /usr/lib/vcac/server/webapps

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.
