CVE-2021-43575: KNX Engineering Tool Software 6

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

KNX ETS6 through 6.0.0 uses the hard-coded password ETS5Password, with a salt value of Ivan Medvedev, allowing local users to read project information, a similar issue to CVE-2021-36799. NOTE: The vendor disputes this because it is not the responsibility of the ETS to securely store cryptographic key material when it is not being exported
