unauthorized access to view and edit monitoring, configuration, and payment
information.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of SiteOmat, software for fuel station management, are
affected:
o SiteOmat versions prior to 6.4.414.122 only are vulnerable to stack-based
buffer overflow CVE-2017-14854 and Code Injection CVE-2017-14853
o SiteOmat Versions prior to 6.4.414.084
3.2 VULNERABILITY OVERVIEW
3.2.1 USE OF HARD-CODED CREDENTIALS CWE-798
The application utilizes hard coded username and password credentials for
application login.
CVE-2017-14728 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.2 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79
The application web interface does not properly neutralize user-controllable
input, which could allow cross-site scripting.
CVE-2017-14850 has been assigned to this vulnerability. A CVSS v3 base score of
6.1 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:R/S:C/
C:L/I:L/A:N ).
3.2.3 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN AN SQL COMMAND ('SQL
INJECTION') CWE-89
The application does not properly sanitize external input, which may allow an
attacker to access the product by specially crafted input.
CVE-2017-14851 has been assigned to this vulnerability. A CVSS v3 base score of
9.4 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:L ).
3.2.4 MISSING ENCRYPTION OF SENSITIVE DATA CWE-311
The application transmits information in plain text, including credentials,
which could allow an attacker with access to transmitted data to obtain
credentials and bypass authentication.
CVE-2017-14852 has been assigned to this vulnerability. A CVSS v3 base score of
8.6 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:L/A:L ).
3.2.5 IMPROPER CONTROL OF GENERATION OF CODE ('CODE INJECTION') CWE-94
The application does not properly restrict syntax from external input, which
could allow unauthenticated users to execute specially crafted code on the
target system.
CVE-2017-14853 has been assigned to this vulnerability. A CVSS v3 base score of
8.6 has been assigned; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/C:L/
I:H/A:L ).
3.2.6 STACK-BASED BUFFER OVERFLOW CWE-121
The application utilizes a function that accepts user input. This input is not
properly validated, which could allow an attacker to execute arbitrary code.
CVE-2017-14854 has been assigned to this vulnerability. A CVSS v3 base score of
9.1 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:N/I:H/A:H) .

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
o 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.
o Restrict system access to authorized personnel only and follow a least
privilege approach.
o Apply defense-in-depth strategies.
o Disable unnecessary accounts and services.
NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
NCCIC 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
on the ICS-CERT website in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to NCCIC for tracking
and correlation against other incidents.
