remediations

Vendor fix, mitigation, or workaround guidance, as published by each source.

A vendor fix is available.

  • FixedFirmware <=1.9.x installed on Hardware XKM3000 L MEDmiele_psirt

    A security patch will be installed on the devices during regular maintenance and device requalification by the Miele customer service or authorized service partners.

  • MitigationFirmware <=1.9.x installed on Hardware XKM3000 L MEDmiele_psirt

    The intended use of the devices and the networking functionalities do not require internet connection. Please operate the devices only in a secure local network to further reduce the risk.

  • Mitigationpepperl_fuchs_psirt

    An external protective measure is required. - Minimize network exposure for affected products and ensure that they are not accessible via the Internet. - Isolate affected products from the corporate network. - If remote access is required, use secure methods such as virtual private networks (VPNs).

  • VDE-2020-024Miele: Treck TCP/IP Vulnerabilities (Ripple20) affecting Communication Module XKM3000 L MED2020-07-08csaf · miele_psirtDE

    For process data documentation purposes the laboratory washers, thermal disinfectors and washer-disinfectors can be integrated in a TCP/IP network by utilizing the affected communication module. The communication module is separate from the actual device control and uses a chipset from Digi International. The TCP / IP stack required for networking is implemented in this chipset with the help of a 3rd party library from Treck. External security researchers have identified several security holes in this library called Ripple20. The most critical vulnerability allows an external attacker to execute arbitrary code on the chip and thus also on the communication module. The above named communication module can be integrated into the following laboratory washers, thermal disinfectors and washer- disinfectors: - PG 8581 - PG 8582 - PG 8583 - PG 8583 CD - PG 8591 - PG 8582 CD - PG 8592 - PG 8593 - PG 8562
