Title
The at daemon must not execute group-writable or world-writable programs. (Cat II impact)
Discussion
If the at facility executes group- or world-writable programs, it is possible for the programs to be accidentally or maliciously changed or replaced without the owner's intent or knowledge. This would cause a system security breach.
Check Content
List the at jobs on the system. Procedure: # ls -lLa /var/spool/cron/atjobs For each at job file, determine which programs are executed. # more <at job file> Check each program executed by at for group- or world-writable permissions. # ls -lLa <at program file> If at executes programs that are group- or world-writable, this is a finding.
Fix Text
Remove group-write and world-write permissions from files executed by at jobs. # chmod go-w <file>
