GEN002460-ESXI5-20047 - The system must be checked weekly for unauthorized setgid files, as well as, unauthorized modification to authorized setgid files.

Information

Files with the setgid bit set will allow anyone running these files to be temporarily assigned the GID of the file. While many system files depend on these attributes for proper operation, security problems can result if setgid is assigned to programs that allow reading and writing of files, or shell escapes.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure the system to check for unauthorized setgid 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.
