SV-61073r1_rule The system must disable TCP reverse IP source routing.

Vulnerability discussion

If enabled, reverse IP source routing would allow an attacker to more easily complete a three-way TCP handshake and spoof new connections.

Check content

Determine if TCP reverse IP source routing is disabled. # ipadm show-prop -p _rev_src_routes -co current tcp If the output of this command is not "0", this is a finding.

Fix text

The Network Management profile is required. Disable reverse source routing. # pfexec ipadm set-prop -p _rev_src_routes=0 tcp

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.
