SV-51282r3_rule The system must be checked for extraneous device files at least weekly.

Vulnerability discussion

If an unauthorized device is allowed to exist on the system, there is the possibility the system may perform unauthorized operations.

Check content

Ask the SA if the system is checked for extraneous device files on a weekly basis. To manually perform the check, disable lock down mode, enable the ESXi Shell, and execute the following command: # find / \( -type b -o -type c \) -exec ls -lL {} \; Re-enable lock down mode. If no automated or manual process is in place, this is a finding.

Fix text

Configure the system to check for extraneous device files on a weekly basis. Refer to the Check Content section above for the basic command structure to search the file system. Additionally, ensure persistence of the command output by storing results to a target located on persistent storage.

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.
