Vulnerability discussion

If Sendmail is not configured to log at level 9, system logs may not contain the information necessary for tracking unauthorized use of the sendmail service.

Check content

The sendmail.cf log level option line will typically appear as follows: O LogLevel=N Check if Sendmail logging is set to level 9 via the following command: # cat /etc/mail/sendmail.cf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v "^#" | \ grep -i loglevel | tr '\011' ' ' | tr -d ' ' | cut -f 2,2 -d "=" If logging is not set, i.e., line is missing or commented, this is a finding. If logging is set to less than 9, this is a finding.

Fix text

Edit the sendmail.cf file, locate the entry (and where necessary uncomment it and/or create it) and modify/set it to 9.

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.
