CVSS v3 9.8 ATTENTION: Remotely exploitable/low skill level to exploit. Vendor: OPW Fuel Management Systems Equipment: SiteSentinel Integra and SiteSentinel iSite Vulnerabilities: Missing Authentication for Critical Function, SQL Injection AFFECTED PRODUCTS OPW Fuel Management Systems (OPW) reports that the vulnerabilities affect SiteSentinel Integra 100, SiteSentinel Integra 500, and SiteSentinel iSite ATG consoles with the following software versions: Older than V175, V175-V189, V191-V195, and V16Q3.1 IMPACT Successful exploitation of these vulnerabilities could allow an unauthorized user to create an account on the device or access the devices database. MITIGATION OPW considers this a critical issue that needs to be addressed immediately. They have issued Service Bulletin 462 and a letter to users to inform them of the availability of free upgrades (firmware Version 17Q2.1) to mitigate these vulnerabilities. OPW recommends that users upgrade all affected systems even if they are already protected from exploitation by running off-line or located on a protected network. OPW has released instructions telling users how to update to the newest firmware version. For specific step-by-step instructions on how to save settings, backup database, and install the new firmware, see the upgrade procedure (M00-20-4438) at the following location: http://www.opwglobal.com/docs/libraries/manuals/electronic-systems/opw-fms-manuals/m00-20-4438-integra-software-upgrade.pdf?sfvrsn=14 (link is external) More information can also be found in the configuration guide: http://www.opwglobal.com/opw-fms/tech-support/manuals-how-to-videos/technical-manuals (link is external) For additional assistance, users and distributors may call the technical service line at 877-OPW-TECH (877-679-8324). OPW has also dedicated an additional phone number specifically for addressing this issue: 312-244-0632. Users may also email FMSOrders@DoverFS.com (link sends e-mail) or contact their commercial district manager. 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 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. 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. VULNERABILITY OVERVIEW MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306 An attacker may create an application user account to gain administrative privileges.
