AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that relies on UDP source port randomization are indirectly affected as well on the Linux Based Products (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4, SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7 LTE EU: Version

1 / 4

Remedy

The mitigation is to disable ICMP destination unreachable messages. The commands to disable UDP port unreachable ICMP reply messages: iptables -I OUTPUT -p icmp --icmp-type destination-unreachable -j DROP service iptables save For additional information about "service iptables save" please read https://access.redhat.com/solutions/1597703 It is not recommended to apply this rule if host being used as forwarder (router) of IP packets. Or it is possible to use this firewall-cmd instead of iptables and the result is similar: firewall-cmd --permanent --direct --add-rule ipv4 filter OUTPUT 0 -p icmp --icmp-type destination-unreachable -j DROP
