CVE-2020-15791
MediumCVSS 6.5Summary
Zidentyfikowano podatność w rodzinie CPU SIMATIC S7-300, S7-400, WinAC RTX (F) 2010 oraz SINUMERIK 840D sl. Protokół uwierzytelniania między klientem a PLC przez port 102/tcp (ISO-TSAP) niewystarczająco chroni przesyłane hasło.
Risk Assessment
Atakujący, który jest w stanie przechwycić ruch sieciowy, może uzyskać ważne dane uwierzytelniające PLC, co stwarza poważne zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się wdrożenie dodatkowych środków ochrony, takich jak szyfrowanie komunikacji oraz monitorowanie ruchu sieciowego w celu wykrywania nieautoryzowanych prób dostępu.

Original NVD description (English source)
A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC S7-400 CPU family (incl. SIPLUS variants) (All versions), SIMATIC WinAC RTX (F) 2010 (All versions), SINUMERIK 840D sl (All versions). The authentication protocol between a client and a PLC via port 102/tcp (ISO-TSAP) insufficiently protects the transmitted password. This could allow an attacker that is able to intercept the network traffic to obtain valid PLC credentials.
