Vulnerability discussion

Log data is essential in the investigation of events. The accuracy of the information is always pertinent. Information that is not accurate does not help in the revealing of potential security risks and may hinder the early discovery of a system compromise. One of the first steps an attacker will undertake is the modification or deletion of log records to cover his tracks and prolong discovery.The web server must protect the log data from unauthorized modification. This can be done by the web server if the web server is also doing the logging function. The web server may also use an external log system. In either case, the logs must be protected from modification by non-privileged users.

Check content

Find any files that are not owned by admin or not group owned by admin, execute the following command: ls -lR /storage/log/vcops/log/product-ui/* | grep -vE 'pid$' | awk '$3 !~ /^admin/ {print}' If the command produces any output, this is a finding.

Fix text

At the command prompt, execute the following command: chown admin:admin Note: Replace with any listed files.

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.
