ATTENTION: Exploitable remotely/low skill level to exploit
Vendor: Rockwell Automation
Equipment: Factory Talk Activation Manager
Vulnerabilities: Cross-site Scripting, Improper Restriction of Operations within the Bounds of a Memory Buffer
This updated advisory is a follow-up to the updated advisory titled ICSA-18-102-02 Rockwell Automation FactoryTalk Activation Manager (Update A) that was published May 24, 2018, on the NCCIC/ICS-CERT website.
Successful exploitation of these vulnerabilities could allow a remote attacker to access sensitive information, rewrite content, or cause a buffer overflow that could result in remote code execution.
Rockwell Automation reports these vulnerabilities affect licensing management software in the following FactoryTalk Activation Manager products:
The following products require FactoryTalk Activation Manager to store and keep track of Rockwell Automation software products and activation files. Users who recognize products from the following list are using FactoryTalk Activation Manager:
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).
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).
Rockwell Automation reported these vulnerabilities to NCCIC.
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.
