Vulnerability from csaf_ncscnl - Published: 2026-01-13 19:17 - Updated: 2026-01-13 19:17Summary
Kwetsbaarheden verholpen in Microsoft Azure
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
Microsoft heeft kwetsbaarheden verholpen in diverse Azure-componenten.
Interpretaties
Een kwaadwillende kan de kwetsbaarheden misbruiken om zich verhoogde rechten toe te kennen en zo toegang te krijgen tot gevoelige gegevens of code uit te voeren waartoe de kwaadwillende aanvankelijk niet is geautoriseerd.
Voor succesvol misbruik moet de kwaadwillende over voorafgaande authenticatie beschikken in het kwetsbare systeem.
