Feiten: Apache heeft meerdere kwetsbaarheden verholpen in Apache CloudStack, specifiek in versies 4.12.0.0 tot en met 4.22.1.0.
Interpretaties: De kwetsbaarheden betreffen onder andere OS Command Injection in de NAS backup provider plugin, Server-Side Request Forgery (SSRF) in verschillende modules zoals metalink mirror URL resolutie en webhook, onvoldoende toegangscontrole in userdata-gerelateerde API's, OAuth en LDAP authenticatie plugins, en improper privilege management in de two-factor authentication plugin.
Verder zijn er kwetsbaarheden in de user interface met betrekking tot onjuiste encoding of escaping, command injection in diagnostics APIs, en improper access control in Kubernetes Service plugin en annotation APIs. Ook is er een kwetsbaarheid in de SAML certificaatvalidatie die het mogelijk maakt om authenticatie te omzeilen.
Sommige kwetsbaarheden maken het mogelijk voor geauthenticeerde gebruikers om root- of administratieve commando's uit te voeren op KVM hypervisor hosts, systeem virtual machines en virtual routers, of om ongeautoriseerde toegang te verkrijgen tot gevoelige informatie en tenant data. Daarnaast is er een kwetsbaarheid in de listHostTags API die domeinrestricties kan omzeilen, en een issue in projectrollenbeheer door domeinbeheerders.
De kwetsbaarheden zijn aanwezig in meerdere opeenvolgende versies van Apache CloudStack en betreffen zowel core functionaliteiten als plugins en API's.
Oplossingen: Apache heeft updates uitgebracht in versies 4.20.3.1 en 4.22.1.1 of later om de genoemde kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
