Vulnerability 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 file permissions for the MIB files. # find / -name *.mib -print # aclget [mib file] If the extended attributes are not disabled, this is a finding.

Fix text

Remove the extended ACL from the MIB file(s) and change extended attributes to disabled. #acledit [mib file]

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
