SV-28431r1_rule The syslog daemon must not accept remote messages unless it is a syslog server documented using site-defined procedures.

Vulnerability discussion

Unintentionally running a syslog server accepting remote messages puts the system at increased risk. Malicious syslog messages sent to the server could exploit vulnerabilities in the server software itself, could introduce misleading information in to the system's logs, or could fill the system's storage leading to a Denial of Service.

Check content

# svcprop system-log | grep log_from_remote If the config/log_from_remote value is not false, this is a finding.

Fix text

# svccfg -s system-log setprop config/log_from_remote=false # svcadm refresh system-log

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.
