Fortinet w najnowszej aktualizacji swojego oprogramowania FortiOS 6.4.13 wprowadził wiele znaczących zmian. Wśród nich możemy wyróżnić np.: zmiany w wykrywaniu urządzeń i licencjonowaniu FortiClient Endpoint Telemetry. W celu zwiększenia bezpieczeństwa system FortiOS 6.4.13 używa opcji, która pozwala na kontrolowanie minimalnej wersji protokołu SSL używanej w komunikacji między FortiGate a usługami SSL i TLS innych firm. Po więcej o najnowszym wydaniu w artykule poniżej.
FortiOS 6.4.13 rozwiązuje kilka istotnych problemów i wyzwań dotyczących oprogramowania. Jedne z najważniejszych problemów, które zostały rozwiązane w tej aktualizacji:
1.Problem z Explict Proxy, który uniemożliwiał dostęp do witryn HTTPS, jeśli w polityce proxy była ustawiona inspekcja certyfikatów,
2.Problem z Firewall, gdzie wyłączona polityka blokująca z obiektami serwera wirtualnego nie mogła zostać włączona po restarcie urządzenia.
3.Gdy lokalnemu administratorowi FortiGate przypisane były więcej niż dwa VDOM-y i próbował się zalogować do konsoli GUI, otrzymał błąd analizy poleceń przy wejściu w tryb konfiguracji VDOM.

Znane problemy:
FortiOS 6.4.13 wprowadza rozwiązania dla problemów dotyczących np.: Opcja „Reject” może być wybrana jako działanie na liście blokującej/zezwalań w Anti-Spam w interfejsie graficznym. Strony FortiView z źródłem FortiAnalyzer nieprawidłowo wyświetlają błąd ” Failed to retrieve data error” na wszystkich widokach VDOM, gdy istnieje nowo utworzony niezarejestrowany VDOM. To tylko przykładowe problemy, więcej można przeczytać w tabeli poniżej
Anti Spam
| Bug ID | Description |
|---|---|
| 877613 | Mark as Reject can be still chosen as an Action in an Anti-Spam Block/Allow List in the GUI. |
Anti Virus
| Bug ID | Description |
|---|---|
| 752420 | If a .TAR.BZ2 or .TAR.GZ archive contains an archive bomb inside its compressed stream, the AV engine will time out. |
Firewall
| Bug ID | Description |
|---|---|
| 719311 | On the Policy & Objects > Firewall Policy page in 6.4.0 onwards, the IPv4 and IPv6 policy tables are combined but the custom section name (global label) is not automatically checked for duplicates. If there is a duplicate custom section name, the policy list may show empty for that section. This is a display issue only and does not impact policy traffic.
Workaround: rename the custom section to unique name between IPv4 and IPv6 policies. |
| 770541 | Within the Policy & Objects menu, the firewall, DoS, and traffic shaping policy pages take around five seconds to load when the FortiGate cannot reach the FortiGuard DNS servers.
Workaround: set the DNS server to the FortiGuard DNS server. |
| 843554 | If the first firewall service object in the service list (based on the order in the command line table) has a protocol type of IP, the GUI may incorrectly modify its protocol number whenever a new firewall service of the same protocol type IP is created in the GUI.
This silent misconfiguration can result in unexpected behavior of firewall policies that use the impacted service. For example, some 6K and 7K platforms have firewall service ALL (protocol type IP) as the first service, and this can cause the ALL service to be modified unexpectedly. Workaround: create a new service in the CLI, or move a non-IP type services to the top of the firewall service list. For example, if config firewall service custom
edit "unused"
set tcp-portrange 1
next
move "unused" before "ALL"
end
|
FortiView
| Bug ID | Description |
|---|---|
| 683654 | FortiView pages with FortiAnalyzer source incorrectly display a Failed to retrieve data error on all VDOM views when there is a newly created VDOM that is not yet registered to FortiAnalyzer. The error should only show on the new VDOM view. |
GUI
| Bug ID | Description |
|---|---|
| 440197 | On the System > FortiGuard page, the override FortiGuard server for AntiVirus & IPS Updates shows an Unknown status, even if the server is working correctly. This is a display issue only; the override feature is working properly. |
| 602397 | Managed FortiSwitch and FortiSwitch Ports pages are slow to load when there are many managed FortiSwitches. |
| 653952 | The web page cannot be found is displayed when a dashboard ID no longer exists.
Workaround: load another page in the navigation pane. Once loaded, load the original dashboard page (that displayed the error) again. |
| 688016 | GUI interface bandwidth widget does not show correct data for tunnel interface when ASIC offload is enabled on the firewall policy. |
| 695163 | When there are a lot of historical logs from FortiAnalyzer, the FortiGate GUI Forward Traffic log page can take time to load if there is no specific filter for the time range.
Workaround: provide a specific time range filter, or use the FortiAnalyzer GUI to view the logs. |
| 743477 | On the Log & Report > Forward Traffic page, filtering by the Source or Destination column with negation on the IP range does not work. |
HA
| Bug ID | Description |
|---|---|

| 760560 | The timestamp on the hyperscale SPU of a deny policy (policy id 0) is incorrect. |
| 796368 | Traffic shaping profile does not seem to have an effect on TCP/UDP traffic in hyperscale. |
| 802369 | Large client IP range makes fixed allocation usage relatively limited. |
Intrusion Prevention
| Bug ID | Description |
|---|---|
| 654307 | Wrong direction and banned location by quarantine action for ICMP.Oversized.Packet in NGFW policy mode. |
| 763736 | IPS custom signature logging shows (even after being disabled) after upgrading to FortiOS 6.4.7. |
Log & Report
| Bug ID | Description |
|---|---|
| 860822 | When viewing logs on the Log & Report > System Events page, filtering by domain\username does not display matching entries.
Workaround: use a double backslash (domain\\username) while filtering or searching by username only without the domain. |
Proxy
| Bug ID | Description |
|---|---|
| 604681 | WAD process with SoC SSL acceleration enabled consumes more memory usage over time, which may lead to conserve mode.
Workaround: disable SoC SSL acceleration under the firewall SSL settings. |
