CVE-2021-43575 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
