Vulnerability discussion

A web server is designed to deliver content and execute scripts or applications on the request of a client or user. Containing user requests to files in the directory tree of the hosted web application and limiting the execution of scripts and applications guarantees that the user is not accessing information protected outside the application's realm.By checking that no symbolic links exist in the document root, the web server is protected from users jumping outside the hosted application directory tree and gaining access to the other directories, including the system root.

Check content

At the command prompt, execute the following command: ls -lR /usr/lib/vmware-vcops/tomcat-web-app | grep '^l' If the command produces any output other than the expected result below, this is a finding. Expected Result: lrwxrwxrwx 1 admin admin 33 Mar 6 03:37 logs -> /storage/log/vcops/log/product-ui lrwxrwxrwx 1 admin admin 47 Mar 6 03:37 vcops-web-ent -> /usr/lib/vmware-vcops/tomcat-web-app/webapps/ui

Fix text

At the command prompt, execute the following command: Note: Replace for the name of any files that were returned. unlink Repeat the commands for each file that was returned.

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.
