Omschrijving
Fortinet heeft kwetsbaarheden verholpen in FortiWeb (Versies 7.0 tot 8.0.1).
De kwetsbaarheden omvatten een mogelijkheid voor remote ongeauthenticeerde aanvallers om hostname-beperkingen te omzeilen, een OS command injection kwetsbaarheid binnen de FortiWeb API, en de mogelijkheid om authenticatie rate-limits te omzeilen. Daarnaast zijn er kwetsbaarheden gerapporteerd die leiden tot stack-based buffer overflows en een NULL Pointer Dereference, die kunnen worden misbruikt door geauthenticeerde aanvallers. Deze kwetsbaarheden kunnen resulteren in ongeautoriseerde toegang, uitvoering van willekeurige commando's, en verstoring van de beschikbaarheid van de FortiWeb service.
Oplossingen
Fortinet heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
