Summary
Kwetsbaarheden verholpen in Fortinet FortiSandbox

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.

Feiten: Fortinet heeft kwetsbaarheden verholpen in FortiSandbox.
Interpretaties: De kwetsbaarheid met kenmerk CVE-2026-107656 heeft een CVSS-score van 9,6 en betreft een authenticatieomzeiling in de webmanagementinterface van FortiSandbox. Een niet-geauthenticeerde kwaadwillende kan via speciaal vervaardigde HTTP-verzoeken de authenticatie omzeilen en ongeautoriseerd code of commando's uitvoeren. De kwetsbaarheden met kenmerk CVE-2026-106172 en CVE-2026-106170 zijn beide als middelmatig ingeschaald. CVE-2026-106172 betreft het gebruik van een hardcoded cryptografische sleutel in de Fabric API, waardoor een niet-geauthenticeerde kwaadwillende mogelijk verhoogde toegangsrechten kan verkrijgen. CVE-2026-106170 betreft een niet-afgevangen uitzondering (exception) en kan door een kwaadwillende met verhoogde rechten worden misbruikt om de werking van de GUI en CLI blijvend te verstoren.
Oplossingen: Fortinet heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Voor FortiSandbox PaaS gelden overeenkomstige update- of migratie-instructies. Zie bijgevoegde referenties voor meer informatie.
