Feiten: Cisco heeft meerdere kwetsbaarheden verholpen in Cisco Integrated Management Controller (IMC).
Interpretaties: De kwetsbaarheden bevinden zich in de webgebaseerde managementinterface van Cisco IMC. Een onbevoegde externe aanvaller kan via de functionaliteit voor het wijzigen van wachtwoorden de authenticatie omzeilen door speciaal opgemaakte HTTP-verzoeken te versturen, wat leidt tot ongeautoriseerde administratieve toegang. Daarnaast kunnen geauthenticeerde aanvallers, waaronder gebruikers met alleen leesrechten, door onvoldoende inputvalidatie command injection uitvoeren en willekeurige root-commando's of code uitvoeren, wat resulteert in privilege-escalatie en volledige controle over het systeem. Verder zijn er meerdere cross-site scripting (XSS) kwetsbaarheden, waaronder opgeslagen en gereflecteerde XSS, die geauthenticeerde gebruikers met administratieve rechten in staat stellen om kwaadaardige scripts te injecteren en uit te voeren in browsers van gebruikers die met de interface werken. Ook kunnen onbevoegde externe aanvallers via gereflecteerde XSS kwetsbaarheden kwaadaardige scripts injecteren door gebruikers te verleiden op speciaal opgemaakte links te klikken, wat kan leiden tot sessiekaping en ongeautoriseerde acties binnen de context van de getroffen gebruikers. Alle kwetsbaarheden zijn het gevolg van onvoldoende inputvalidatie in de webinterface van Cisco IMC. Voor succesvol misbruik moet de kwaadwillende toegang hebben tot de management-interface. Het is goed gebruik een dergelijke interface niet publiek toegankelijk te hebben, maar af te steunen in een separate beheeromgeving.
Oplossingen: Cisco heeft updates uitgebracht om de kwetsbaarheden in Cisco Integrated Management Controller te verhelpen. Zie bijgevoegde referenties voor meer informatie.
