Vulnerability discussion

The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification. The file also contains password hashes which must not be accessible to users other than root.

Check content

For Trusted Mode: Check the TCB auth files and directories. # ls -lLd /tcb /tcb/files /tcp/files/auth # ls -lL /tcb/files/auth/[a-z,A-Z]/* If the group-owner of any of the /tcb files and directories is not root, bin, sys, or other, this is a finding. For SMSE: Check the /etc/shadow file. # ls -lL /etc/shadow If the /etc/shadow file is not group-owned by root, bin, sys or other, this is a finding.

Fix text

For Trusted Mode: # chgrp root /tcb #chgrp root /tcb/files /tcb/files/auth # chgrp root /tcb/files/auth/[a-z]/* For SMSE: # chgrp root /etc/shadow

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.
