MEDIUM 5.9EPSS 0.57%

Does this matter?

Lower severity and a low EPSS score (0.57%). Track it; it rarely justifies an emergency change on its own.

Description

Siemens LOGO! Soft Comfort (All versions before V8.2) lacks integrity verification of software packages downloaded via an unprotected communication channel. This could allow a remote attacker to manipulate the software package while performing a Man-in-the-Middle (MitM) attack.
