Feiten
Arista Networks heeft kwetsbaarheden verholpen in DANZ.
Interpretaties
De kwetsbaarheden omvatten verschillende manieren waarop geauthenticeerde gebruikers met beperkte rechten toegang kunnen krijgen tot gevoelige systemen en gegevens. Dit omvat het ontsnappen aan de CLI-sandbox, het misbruiken van SSH-portforwarding, en het persistent maken van besturingssysteemoperaties na een sessietimeout. Daarnaast kunnen gebruikers via een debug-API ongeautoriseerde toegang krijgen tot gevoelige configuratiegegevens, zoals gebruikerswachtwoord-hashes. Tot slot kan de cryptografische validatie van upgrade-afbeeldingen worden ondermijnd door het invoegen van speciaal vervaardigde bestanden in de upgrade-ISO, wat kan leiden tot ongeautoriseerde wijzigingen.
Oplossingen
De vendor heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
