o CRITICAL INFRASTRUCTURE SECTORS: Transportation Systems
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: Italy
3.4 RESEARCHER
Hanno Bock reported these vulnerabilities to CISA.
4. MITIGATIONS
alpitronic recommends users change the default credentials for all charging
devices.
alpitronic advises that the interface should be connected only to internal
segregated and access-controlled networks and not exposed to the public
internet/web.
When informed of these vulnerabilities, alpitronic, in conjunction with and/or
on behalf of affected clients, disabled the interface on any exposed devices
and all clients were contacted directly and reminded that the interface is not
intended to be visible on the public Internet and that default passwords should
be changed.
alpitronic are also applying mitigations to all devices in the field and to new
devices in production. New devices will come with unique passwords. Devices
using the default password will be automatically assigned new unique passwords,
or at first access if the device has not yet been installed. Devices with the
default passwords already changed will not be affected. New passwords can be
obtained by scanning the QR-Code inside the charger or in DMS portal hyperdoc.
Contact Hypercharger support with any questions about newly assigned passwords.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability, such as:
o Minimize network exposure for all control system devices and/or systems,
ensuring they are not accessible from the internet .
o Locate control system networks and remote devices behind firewalls and
isolating them from business networks.
o When remote access is required, use more secure methods, such as Virtual
Private Networks (VPNs), recognizing VPNs may have vulnerabilities and
should be updated to the most current version available. Also recognize VPN
is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage on cisa.gov/ics . Several CISA products detailing cyber
defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies .
CISA encourages organizations to implement recommended cybersecurity strategies
for proactive defense of ICS assets .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics in the technical information paper,
ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.
No known public exploitation specifically targeting this vulnerability has been
reported to CISA at this time.
