4.2 VULNERABILITY OVERVIEW

4.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79

A Cross-Site Scripting (?XSS?) vulnerability was found in certain versions of
Wibu-Systems CodeMeter that may allow local attackers to inject arbitrary web
script or HTML via a specific field in a configuration file, allowing an
attacker to access sensitive information, or even rewrite the content of the
HTML page.

CVE-2017-13754 has been assigned to this vulnerability. A CVSS v3 base score of
2.7 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:C/C:N
/I:L/A:N).

4.2.2 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER
CWE-119

A custom string copying function of the license server manager in FlexNet
Publisher does not use proper bounds checking on incoming data, allowing a
remote, unauthenticated user to send crafted messages with the intent of
causing a buffer overflow.

CVE-2015-8277 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).

4.3 BACKGROUND

  * Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Food and
    Agriculture, Water and Wastewater Systems
  * Countries/Areas Deployed: Worldwide
  * Company Headquarters Location: U.S.

4.4 RESEARCHER

Rockwell Automation reported these vulnerabilities to NCCIC.

5. MITIGATIONS

Rockwell Automation recommends users with affected versions of CodeMeter and/or
FlexNet Publisher that were installed with FactoryTalk Activation Manager to
update Factory Talk Activation Manager to v4.02. If unable to update
FactoryTalk Activation Manager to v4.02, update CodeMeter to a compatible
version of CodeMeter that is compatible with FactoryTalk Activation Manager.

Rockwell Automation also encourages users to combine the updates above with
these general security guidelines to employ multiple strategies simultaneously.

  * Block all traffic to EtherNet/IP or other CIP protocol-based devices from
    outside the Manufacturing Zone by blocking or restricting access to Port
    2222/TCP and UDP and Port 44818/TCP and UDP, using proper network
    infrastructure controls, such as firewalls, UTM devices, or other security
    appliances. For more information on TCP/UDP ports used by Rockwell
    Automation Products, see Knowledgebase Article ID 898270 available at:
    https://rockwellautomation.custhelp.com/app/answers/detail/a_id/898270/page
    /1 (Login required)
  * Minimize network exposure for all control system devices and/or systems,
    and ensure they are not accessible from the Internet.
  * Locate control system networks and 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. VPN is only as secure as
    the connected devices

mitigations, please see Rockwell Automation Knowledgebase Advisory 1073133
