VectorAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions SENTRON 3KC ATC6 Expansion Module Ethernet (3KC9000-8TL75) (All versions)
Description A vulnerability has been identified that exposes an unused, unstable http service at port 80/tcp on the Modbus-TCP Ethernet. This could allow an attacker on the same Modbus network to create a denial of service condition that forces the device to reboot. The vulnerability is also related to undocumented configuration commands. Exploitation of the vulnerability may allow a remote attacker to cause a denial of service.
Recommendations As a temporary workaround, consider disabling the http service at port 80/tcp on the Modbus-TCP Ethernet until a patch is available. Restrict access to the Modbus network to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
