"The remote device is missing a vendor-supplied security patch.");
  script_set_attribute(attribute:"description", value:
"The BIG-IP system fails to perform martian address filtering (as
defined in RFC 1812, section 5.3.7) for control plane tasks on the
management interface. This may allow attackers on an adjacent system
to force the BIG-IP system into processing packets with spoofed source
addresses. (CVE-2019-6654)

Note : A martian packet is an IP packet on the public internet that
contains a source or destination address that is reserved for special
use by the Internet Assigned Numbers Authority (IANA).

Note : Adjacent systems are IP network systems that are configured on
same logical network subnet.

Impact

This vulnerability allows for remote unauthorized modification or
disruption of service.");
