Vulnerability discussion

The web server's private key is used to prove the identity of the server to clients and securely exchange the shared secret key used to encrypt communications between the web server and clients.By gaining access to the private key, an attacker can pretend to be an authorized server and decrypt the SSL traffic between a client and the web server.tc Server stores the server's private key in a keystore file. The vRA keystore file is tcserver.keystore, and this file must be protected to only allow system administrators and other authorized users to have access to it.

Check content

At the command prompt, execute the following command: ls -al /opt/vmware/horizon/workspace/conf/tcserver.keystore Verify that file permissions are set to "640" or more restrictive. Verify that the owner is horizon and group-owner is www. If either of these conditions are not met, this is a finding.

Fix text

At the command prompt, execute the following commands: chown horizon:www /opt/vmware/horizon/workspace/conf/tcserver.keystore chmod 640 /opt/vmware/horizon/workspace/conf/tcserver.keystore

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.
