Summary
SolarWinds heeft meerdere kwetsbaarheden verholpen in Serv-U.
Details
Interpretaties
De kwetsbaarheden in SolarWinds Serv-U betreffen voornamelijk insecure direct object reference (IDOR) en broken access control. Deze maken het mogelijk voor aanvallers met bepaalde privileges, zoals domain administrator of group administrator toegang, om privileges te escaleren naar system administrator of root-niveau. Hierdoor kunnen zij op afstand willekeurige code uitvoeren en systeembeheerrechten verkrijgen.
Sommige kwetsbaarheden maken het ook mogelijk om SMTP-sessies te kapen, accounts over te nemen, of persistent cross-site scripting (XSS) uit te voeren die sessies van beheerders kan compromitteren. De impact van deze kwetsbaarheden is op Windows-omgevingen doorgaans minder groot dan op andere platformen. Exploitatie vereist meestal dat de aanvaller al beschikt over geauthenticeerde toegang met hoge privileges, zoals domain administrator rechten.
De verholpen kwetsbaarheden betreffen zoals gezegd overwegend kwetsbaarheden die kunnen worden misbruikt in zo genaamde 'Evil Admin'-scenario's. Dit soort kwetsbaarheden zijn doorgaans niet eenvoudig te misbruiken door ongeathenticeerde kwaadwillenden op afstand. Echter zijn er in deze updates dermate veel verholpen dat het aan te raden is om, naast het inzetten van de updates, te controleren hoe de rechtenstructuur is geïmplementeerd. Dit geldt voornamelijk voor onderdelen die publiek toegankelijk zijn.
Oplossingen
SolarWinds heeft updates uitgebracht om de kwetsbaarheden in Serv-U te verhelpen. Zie bijgevoegde referenties voor meer informatie.
