OVERVIEW
Independent researcher Maxim Rupp has identified two vulnerabilities in
Resource Data Managements Data Manager application. Resource Data Management
has produced a new version to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely.
AFFECTED PRODUCTS
Resource Data Management reports that the vulnerabilities affect the following
versions of Data Manager:
Versions prior to 2.2
IMPACT
Privilege escalation allows an attacker to gain elevated access to resources
that are normally protected from an application or user. This includes
altering logs and parameters.
A cross-site request forgery (CSRF) attack may allow the web browser to
perform an unwanted action on a trusted site for which the user is currently
authenticated.
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.
BACKGROUND
Resource Data Management is a UK-based company that maintains offices in
several countries around the world, including the US and Asia.
The affected product, Data Manager, is a web-based SCADA monitoring system.
According to Resource Data Management, Data Manager is deployed across several
sectors including Critical Manufacturing, Healthcare and Public Health, and
Information Technology. Resource Data Management estimates that these products
are used primarily in the US, UK, and in Asia.
VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
PRIVILEGE ESCALATION [a]
A valid user can change the password for any other user, including
administrators, to increase their privileges on the system.
CVE-2015-6470 [b] has been assigned to this vulnerability. A CVSS v3 base score
of 8.8 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). [c]
CROSS-SITE REQUEST FORGERY [d]
A CSRF attack occurs when a malicious program causes a web browser to perform
an unwanted action on a trusted site for which the user is currently
authenticated.
CVE-2015-6468 [e] has been assigned to this vulnerability. A CVSS v3 base score
of 6.5 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). [f]
VULNERABILITY DETAILS
EXPLOITABILITY
These vulnerabilities could be exploited remotely.
EXISTENCE OF EXPLOIT
No known public exploits specifically target these vulnerabilities.
DIFFICULTY
An attacker with a low skill would be able to exploit these vulnerabilities.
MITIGATION
Resource Data Management has developed Data Manager 2.2 that fixes both these
vulnerabilities.
Customers can download Version 2.2 at:
https://www.resourcedm.com/en-us/Support/Download-Software.
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 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 ICSCERT 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.
