IMPACT
Successful exploitation of these vulnerabilities may allow a remote attacker
to gain unauthorized access to the affected system and to issue unexpected
commands to impact the intended operation of the system.
MITIGATION
PDQ Manufacturing, Inc. ("PDQ") has validated the vulnerabilities
and is developing product fixes for the affected systems. In the interim,
PDQ. has identified compensating controls to limit the exploitability of
the affected systems.
PDQ recommends that users apply the following controls:
Always make sure any PDQ equipment is not accessible from the Internet;
it should be behind a secure firewall.
Whenever a machine or router is received and installed, always change
the default password from the factory settings to a new password unique
to the machine. If an existing site is still using the factory default
passwords on a machine or router, immediately change the default
password to a new, unique, strong password.
Always set up the system network (router or Wi-Fi) with its security
features enabled such that they require a username and password to be
able to access the machine network.
Do not set up the site router with "port forwarding" enabled. This
can effectively expose the system to the Internet and may permit an
unauthorized person to reach the machine login screen.
Do not share passwords or write them down in an accessible place where
unauthorized users may find them.
NCCIC/ICS-CERT recommends that users take defensive measures to minimize the
risk of exploitation of these vulnerabilities. Specifically, users should:
Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls,
and isolate them from the business network.
When remote access is required, use secure methods, such as Virtual
Private Networks (VPNs), recognizing that VPNs may have vulnerabilities
and should be updated to the most current version available. Also
recognize that VPN is only as secure as the connected devices.
ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended
practices on the ICS-CERT web page. Several recommended practices are
available for reading and download, including Improving Industrial Control
Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are
publicly available in the ICS-CERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to ICS-CERT for
tracking and correlation against other incidents.
