Vulnerability reported
21 февраля 2020
Description
Data transferred over IXL protocol is unencrypted.
CVSS v3
Exploitability
⚠ Remotely exploitable: network access to port 1131/TCP is required
Attack complexity
Privilege required
User interaction
Confidentiality
Impact
An attacker could read and modify all data transferred between ISaGRAF Workbench and ISaGRAF Runtime if the communication is carried out over IXL protocol.
Affected products
- AADvance Controller:
- All firmware versions
- Based on ISaGRAF Runtime 5 controllers:
- All software versions
- Micro800 family:
- All firmware versions
- ISaGRAF Free Runtime:
- All software versions
Mitigation
Rockwell Automation mitigation
Customers should consider using proper network infrastructure controls, such as firewalls, UTM devices, VPN, or other security appliance.
To reduce risk, customers should ensure they are employing proper network segmentation and security controls. Specifically, network exposure for all control system devices should be minimized, and control systems should be behind firewalls and isolated from other networks when possible. Refer to the Converged Plantwide Ethernet (CPwE) Design and Implementation Guide for best practices deploying network segmentation and broader defense-in-depth strategies.
For ISaGRAF, restrict or block traffic on TCP 1131 from outside of the industrial control system network zone. For more information on the TCP/UDP ports used by ISaGRAF refer to product documentation.
Since ISaGRAF 5 Runtime is provided to a customer as a development kit, implementing least-privilege may vary from implementation to implementation based on the hardware in use.
For AADvance controllers, customers are encouraged to restrict or block traffic on TCP 1132 from outside of the industrial control system network zone.
For Micro800 family, to reduce risk, customers are encouraged to protect the controller with a password.1
