HIMA F30 03X YY (COM) all variants — Schwachstelle CVE-2024-24781

An unauthenticated remote attacker can use an uncontrolled resource consumption vulnerability to DoS the affected devices through excessive traffic on a single ethernet port. 

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CVE-2024-24781: All load limiting measures are helpful (e.g. in external devices or also in the switch of the above mentioned products). Please check whether the reduced speed is still sufficient for the desired application. Protect the network with segregation measures and restrict the access of unauthorized network participants (e.g. close unused ports) CVE-2024-24782: Switching the MAC-learning from 'conservative' to 'tolerant' mitigates the above described vulnerability but leads to potential IP-Spoofing and ARP-Poisoning and should therefore be avoided. HIMax and HIQuad X systems can be setup in the way that real physical segregation (between different modules) is used. E.g. it is impossible to ping from one X-COM to another X-COM in the same Rack. HIMatrix should be used in that way that CPU and COM are NOT connected via VLAN e.g. CPU connected to Port 1 and 2, COM Connected to Port 3 and 4.
