- Feiten
Siemens heeft kwetsbaarheden verholpen in diverse producten als RUGGEDCOM, SCALANCE, SIMATIC en Tecnomatix
- Interpretaties
De kwetsbaarheden stellen een kwaadwillende mogelijk in staat aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade:
- Denial-of-Service (DoS)
- Manipulatie van gegevens
- Omzeilen van een beveiligingsmaatregel
- Omzeilen van authenticatie
- (Remote) code execution (root/admin rechten)
- (Remote) code execution (Gebruikersrechten)
- Toegang tot systeemgegevens
- Toegang tot gevoelige gegevens
- Spoofing
De kwaadwillende heeft hiervoor toegang nodig tot de productieomgeving. Het is goed gebruik een dergelijke omgeving niet publiek toegankelijk te hebben.
- Oplossingen
Siemens heeft beveiligingsupdates uitgebracht om de kwetsbaarheden te verhelpen. Voor de kwetsbaarheden waar nog geen updates voor zijn, heeft Siemens mitigerende maatregelen gepubliceerd om de risico's zoveel als mogelijk te beperken. Zie de bijgevoegde referenties voor meer informatie.
