Feiten
SolarWinds heeft kwetsbaarheden verholpen in Serv-U.
Interpretaties
De kwetsbaarheden bevinden zich in de wijze waarop Serv-U toegang controleert en gegevens types verwerkt. Aanvallers met administratieve privileges kunnen deze kwetsbaarheden misbruiken om ongeautoriseerde systeemtoegang te verkrijgen en willekeurige code met verhoogde rechten uit te voeren. Dit kan leiden tot privilege-escalatie.
Oplossingen
Solarwinds heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
