Omschrijving

Siemens heeft kwetsbaarheden verholpen in diverse producten, zoals SCALANCE, SICAM, Tecnomatix, SITOP en PowerSys.

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 beveiligingsmaatregel
  • (Remote) code execution (Administrator/Root rechten)
  • (Remote) code execution (Gebruikersrechten)
  • Toegang tot systeemgegevens
  • Verhoogde gebruikersrechten

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.
