GEN003360 - The 'at' daemon must not execute group-writable or world-writable programs.
Information
If the 'at' facility executes world-writable or group-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.NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Remove group-write and world-write permissions from files executed by at jobs.Procedure:
# chmod go-w <file>
