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.

Feiten: SonicWall heeft kwetsbaarheden verholpen in de SMA1000 Appliance.
Interpretaties: De SMA1000 Appliance bevat twee kwetsbaarheden. De eerste is een pre-authenticatie Server-Side Request Forgery (SSRF) in de Work Place interface, waarmee een externe, niet-geauthenticeerde aanvaller ongeautoriseerde acties kan uitvoeren. De tweede kwetsbaarheid betreft post-authenticatie remote code execution, waarbij een aanvaller met geldige inloggegevens willekeurige code op afstand kan uitvoeren. Beide kwetsbaarheden zijn als zero-days misbruikt. Het NCSC raadt organisaties aan de advisory van SonicWall op te volgen
Oplossingen: SonicWall heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
