Feiten
Splunk heeft kwetsbaarheden verholpen in Splunk Enterprise en Splunk Cloud Platform.
Interpretaties
De kwetsbaarheden omvatten verschillende problemen, waaronder de mogelijkheid voor laaggeprivilegieerde gebruikers om ongeautoriseerde dashboards te creëren, toegang te krijgen tot gevoelige informatie via mobiele meldingen, en de injectie van ANSI-escape codes in logbestanden. Daarnaast kunnen hooggeprivilegieerde gebruikers ongeautoriseerde JavaScript-code uitvoeren, en zijn er problemen met onjuiste machtigingen die niet-beheerders toegang geven tot installatiebestanden. Deze kwetsbaarheden kunnen leiden tot ongeautoriseerde toegang tot gevoelige gegevens en verstoringen van de applicatiefuncties, wat de integriteit en beschikbaarheid van de systemen in gevaar brengt.
Oplossingen
Splunk heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
