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.

the new versions for each of the affected models, please see Siemens Security
Advisory SSA-284765 at the following location:

http://www.siemens.com/cert/advisories (link is external)

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.
