Feiten
Fortinet heeft kwetsbaarheden verholpen in FortiOS, FortiProxy, FortiWeb en FortiSwitchManager.
Interpretaties
De kwetsbaarheden stellen ongeauthenticeerde aanvallers in staat om toegang te krijgen tot de systemen door gebruik te maken van verschillende technieken, waaronder het omzeilen van FortiCloud SSO-login authenticatie via speciaal vervaardigde SAML-berichten, het behouden van actieve SSLVPN-sessies ondanks een wachtwoordwijziging, en het uitvoeren van ongeautoriseerde operaties via vervalste HTTP- of HTTPS-verzoeken. Dit kan leiden tot ongeautoriseerde toegang tot gevoelige API-gegevens en andere netwerkbronnen.
Oplossingen
Als mitigerende maatregel tegen de authenticatie-bypass kan FortiCloud SSO login worden uitgeschakeld. Fortinet heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
