CVE-2020-15791 (GCVE-0-2020-15791)
Vulnerability from cvelistv5 – Published: 2020-09-09 18:13 – Updated: 2024-08-04 13:22
VLAI?
Summary
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.
Severity ?
No CVSS data available.
