SV-45156r1_rule Local initialization files must not have extended ACLs.

Vulnerability discussion

Local initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon.

Check content

Check user home directories for local initialization files with extended ACLs. # for HOMEDIR in $(cut -d: -f6 /etc/passwd); do find ${HOMEDIR} -type f -name '\.*' | xargs ls -ld | grep '\+'; done If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all

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.
