Omschrijving

Fortinet heeft meerdere kwetsbaarheden verholpen in FortiMail.

De kwetsbaarheden in FortiMail betreffen onder andere OS command injection, path traversal, SQL-injectie, authenticatie- en autorisatieproblemen, argument injection, XML-injectie, en resource consumptie. Sommige kwetsbaarheden kunnen door ongeauthenticeerde aanvallers worden misbruikt, terwijl andere authenticatie vereisen. Exploitatie kan leiden tot het uitvoeren van ongeautoriseerde commando's op root-niveau, het omzeilen van authenticatie en autorisatie, het resetten van wachtwoorden van webmailgebruikers, het lezen en verzenden van versleutelde e-mails namens andere gebruikers, het verwijderen van gebruikers in multi-tenant omgevingen, en het veroorzaken van denial-of-service door crashes of resource uitputting. De kwetsbaarheden beïnvloeden verschillende versies van FortiMail, met name versies tussen 7.2 en 8.0.2, en hebben impact op kernfunctionaliteiten zoals mailverwerking, webmailinterfaces, administratieve interfaces, en integratie met FortiAuthenticator.
