Check: GEN002460

Solaris 10 SPARC STIG: GEN002460 (in versions v2 r4 through v1 r19)

Title

The system must be checked weekly for unauthorized setgid files, as well as, unauthorized modification to authorized setgid files. (Cat II impact)

Discussion

Files with the setgid bit set will allow anyone running these files to be temporarily assigned the group id 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.

Check Content

Determine if a weekly automated or manual process is used to generate a list of setgid files on the system and compare it with the prior list. If no such process is in place, this is a finding.

Fix Text

Establish a weekly automated or manual process to generate a list of setgid files on the system and compare it with the prior list. To create a list of setgid files use the following command. # find / -perm -2000 > setgid-file-list
