Summary
Kwetsbaarheden verholpen in Cisco Identity Services Engine
Notes
The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten: Cisco heeft meerdere kwetsbaarheden verholpen in Cisco Identity Services Engine (ISE) en Cisco ISE Passive Identity Connector (ISE-PIC).
Interpretaties: De kwetsbaarheden kunnen door zowel geauthenticeerde als niet-geauthenticeerde aanvallers worden misbruikt. Een geauthenticeerde aanvaller met administratieve rechten kan speciaal vervaardigde HTTP-verzoeken sturen om willekeurige commando's uit te voeren, wat kan leiden tot Denial-of-Service en privilege-escalatie, waardoor de integriteit en beschikbaarheid van de systemen in het geding komen. Daarnaast kunnen sommige kwetsbaarheden leiden tot ongeautoriseerde informatieontsluiting. Niet-geauthenticeerde aanvallers kunnen eveneens willekeurige code op afstand uitvoeren en toegang krijgen tot gevoelige informatie zoals gehashte inloggegevens. De oorzaak ligt in onjuiste autorisatiecontroles bij toegang tot bepaalde bronnen binnen de systemen.
Oplossingen: Cisco heeft updates uitgebracht om de kwetsbaarheden in Cisco Identity Services Engine en Cisco ISE Passive Identity Connector te verhelpen. Zie bijgevoegde referenties voor meer informatie.
