Vulnerability discussion

Proxy Neighbor Discovery Protocol (NDP) allows a system to respond to NDP requests on one interface on behalf of hosts connected to another interface. If this function is enabled when not required, addressing information may be leaked between the attached network segments.

Check content

Determine if SLES for vRealize has proxy "NDP", and if it is enabled: # more /proc/sys/net/ipv6/conf/*/proxy_ndp If the file is not found, the kernel does not have proxy "NDP", this is not a finding. If the file has a value of "0", proxy "NDP" is not enabled, this is not a finding. If the file has a value of "1", proxy NDP is enabled, this is a finding.

Fix text

Disable proxy "NDP" on the system. For Appliance OS, "proxy_ndp" is disabled by default.

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.
