CVE-2021-28913

Name of the Vulnerable Software and Affected Versions: eibPort V3 versions prior to 3.9.1

Description: The issue allows unauthenticated attackers to access the /webif/SecurityModule to validate the hard-coded unique 'eibPort String', which acts as the root SSH key passphrase. This can be part of an attack chain to gain SSH root access.

Recommendations: For versions prior to 3.9.1, update to version 3.9.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the /webif/SecurityModule endpoint until a patch is available. Avoid using the hard-coded eibPort String as the root SSH key passphrase in the affected versions.
