Vulnerabilities: SQL Injection

AFFECTED PRODUCTS

The following version of IntegraXor, a web SCADA/HMI solution, is affected:

  * Ecava IntegraXor v 6.1.1030.1 and prior.

IMPACT

Successful exploitation of these vulnerabilities could allow an attacker to
disclose sensitive information from the database or generate an error in the
database log.

MITIGATION

Ecava recommends that users of affected IntegraXor versions update to version
6.1.1215.0 or newer, a download for which can be found at the following
location:

https://www.integraxor.com/download-scada/

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.

No known public exploits specifically target these vulnerabilities.
