Vulnerability discussion

After a security incident has occurred, investigators will often review log files to determine what happened. tc Server HORIZON must create a log entry when a user accesses the system and the system authenticates users.The logs must contain information about user sessions to include what type of event occurred, when (date and time) events occurred, where within the server the events occurred, the client source of the events, the outcome (success or failure) of the event, the identity of the user/subject/process associated with the event.As a Tomcat derivative, tc Server can be configured with an “AccessLogValve”. A Valve element represents a component that can be inserted into the request processing pipeline. The pattern attribute of the “AccessLogValve” controls which data gets logged. The “%u” parameter will record the remote user that was authenticated. Knowing the authenticated user could be crucial to know in an investigation.

Check content

At the command prompt, execute the following command: tail /storage/log/vcops/log/suite-api/localhost_access_log.YYYY-MM-dd.txt Note: Substitute the actual date in the file name. If the identity of the user is not being recorded, this is a finding.

Fix text

Navigate to and open /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml. Navigate to and locate . Configure the node with the below. Note: The “AccessLogValve” should be configured as follows:

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.
