IMPACT
A successful exploit of this vulnerability may allow the attacker to obtain
administrative credentials.
Impact to individual organizations depends on many factors that are unique to
each organization. NCCIC/ICS-CERT recommends that organizations evaluate the
impact of this vulnerability based on their operational environment,
architecture, and product implementation.
BACKGROUND
Vanderbilt Industries acquired the SIEMENS IP Cameras business in June 2015
and released updates for the affected camera models under the SIEMENS brand.
The SIEMENS-branded IP-based CCTV cameras portfolio includes a range of
megapixel cameras in various configuration and mounting options. According to
Vanderbilt, these products are deployed across several sectors including
Commercial Facilities, Healthcare and Public Health, and Government
Facilities. Vanderbilt estimates that these products are used worldwide.

Siemens recommends that users operate the devices within trusted networks and
protect network access to the devices with appropriate mechanisms. Siemens
also recommends enabling authentication on the web server.
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.
