Vulnerability from github – Published: 2022-05-24 19:14 – Updated: 2022-05-24 19:14

Details

A vulnerability has been identified in LOGO! CMR2020 (All versions < V2.2), LOGO! CMR2040 (All versions < V2.2), SIMATIC RTU 3000 family (All versions). The underlying TCP/IP stack does not properly calculate the random numbers used as ISN (Initial Sequence Numbers). An adjacent attacker with network access to the LAN interface could interfere with traffic, spoof the connection and gain access to sensitive information.

Severity ?

5.4 (Medium)
