Name of the Vulnerable Software and Affected Versions:
BAB TECHNOLOGIE GmbH eibPort V3 versions prior to 3.9.1
Description:
The issue allows unauthenticated attackers to access the /tmp path, which contains sensitive data such as the device serial number. This information can be used to self-calculate a possible loginId, enabling a brute force attack against the BMX interface. 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 /tmp path and the BMX interface to minimize the risk of exploitation.
