Discussion

The ability to read the MIB file could impart special knowledge to an intruder or malicious user about the ability to extract compromising information about the system or network.

Check Content

Check the modes for all Management Information Base (MIB) files on the system.

Procedure:
# find / -name *mib* -o -name *MIB* | xargs ls -lL

Any file returned with a mode 0640 or less permissive is a finding.

Fix Text

Change the mode of MIB files to 0640.

Procedure:
# chmod 0640 <mib file>
