Unencrypted File Transfer in ISaGRAF Workbench/Runtime

IdentifiersCVE-2020-25178CWE-319· Cleartext Transmission of…

ISaGRAF Workbench communicates with Rockwell Automation ISaGRAF Runtime (versions 4.x and 5.x) over TCP/IP using a proprietary protocol that lacks encryption. This protocol allows for file system operations, including uploading, reading, and deleting files. Because the data is transferred in plaintext, a remote unauthenticated attacker can intercept or manipulate these operations, potentially uploading malicious files or exfiltrating sensitive data.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A remote unauthenticated attacker can upload, read, or delete files on the ISaGRAF Runtime system, leading to potential compromise of the device, loss of sensitive data, or disruption of operations. This could be leveraged for further attacks, including remote code execution if malicious files are uploaded and executed.

Mitigation

If you can’t patch tonight, do this now.

Implement network segmentation and firewall rules to restrict access to the ISaGRAF Runtime systems. Use VPNs or other secure tunnels for remote access. Monitor network traffic for unauthorized file transfer attempts.

Remediation

Patch, then assume compromise.

Upgrade to a version of ISaGRAF Workbench and Runtime that implements encrypted communication for file transfer operations. If no patch is available, restrict network access to the affected systems to trusted hosts only.
