Vulnerability discussion

Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the web server include date and time and must be to a granularity of one second.Like all web servers, tc Server logs can be configured to produce a Common Log Format (CLF). The tc Server component known as an AccessLogValve, which represents a component that can be inserted into the request processing pipeline to capture user interaction. The Access Log Valve should be configured to ensure that investigators have sufficient information to conduct an appropriate audit.

Check content

At the command prompt, execute the following command: tail /storage/log/vmware/horizon/localhost_access_log.YYYY-MM-dd.txt If the timestamp does not contain a minimum granularity of one second, this is a finding. Note: Substitute the actual date in the file name. Note: In Common Log Format, a timestamp will look like [06/Feb/2016:23:12:57 +0000]. The "57" part is the "seconds" part of the timestamp.

Fix text

Navigate to and open /opt/vmware/horizon/workspace/conf/server.xml. Navigate to the node. Set the 'pattern' setting with "%h %l %u %t "%r" %s %b". Note: The node should be configured per the following:

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.
