The owner, group-owner, mode, ACL, and location of files with the setgid bit set must be documented using site-defined procedures.


Overview

Finding ID Version Rule ID IA Controls Severity
V-227707 GEN002440 SV-227707r603266_rule Medium
Description
All 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.

If the ownership, permissions, location, and ACLs of all files with the setgid bit set are not documented, this is a finding.
Fix Text (F-36423r602981_fix)
All files with the setgid bit set will be documented in the system baseline and authorized by the Information Systems Security Officer. Locate all setgid files with the following command.

find / -perm -2000 -exec ls -lLd {} \;

Ensure setgid files are part of the operating system software, documented application software, documented utility software, or documented locally developed software. Ensure none are text files or shell programs.
