Motorola MOSCAD SCADA IP Gateway Vulnerabilities
ICSA： ICS Advisory (ICSA-15-351-02)
Independent researcher Aditya K. Sood has identified Remote File Inclusion (RFI) and Cross-Site Request Forgery (CSRF) vulnerabilities in Motorola Solutions’ MOSCAD IP Gateway. Motorola Solutions has confirmed this product was cancelled at the end of 2012 and no longer offer software updates.
These vulnerabilities could be exploited remotely.
The following MOSCAD IP Gateway versions are affected:
- MOSCAD IP Gateway, all versions.
A successful exploit of these vulnerabilities could allow a remote attacker to perform actions with the permissions of a valid user.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.
Motorola Solutions is a US-based company that maintains offices in 60 countries around the world.
The affected product, MOSCAD IP Gateway, is a SCADA system that has some web-based management capabilities. According to Motorola Solutions, MOSCAD IP Gateways, are deployed across several sectors including Commercial Facilities, Critical Manufacturing, Energy, Water and Wastewater Systems, and others.
Motorola Solutions estimates that these products are used primarily in the United States and Europe with a small percentage in Asia.
REMOTE FILE INCLUSIONa
Files can be accessed and downloaded without authentication.
CVE-2015-7935b has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).c
CROSS-SITE REQUEST FORGERYd
A request can be used to update the password because of no tokens.
CVE-2015-7936e has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).f
These vulnerabilities could be exploited remotely.
EXISTENCE OF EXPLOIT
No known public exploits specifically target these vulnerabilities.
An attacker with a low skill would be able to exploit these vulnerabilities.
Product has been discontinued since the end of 2012; contact Motorola Solutions for support https://www.motorolasolutions.com/.
ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Only use products that are currently maintained and supported by the manufacturer.
- 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 at: http://ics-cert.us-cert.gov/content/recommended-practices. 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 (http://ics-cert.us-cert.gov/).
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.
In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
- Do not click web links or open unsolicited attachments in email messages.
- Refer to Recognizing and Avoiding Email Scamsg for more information on avoiding email scams.
- Refer to Avoiding Social Engineering and Phishing Attacksh for more information on social engineering attacks.
