Summary

ISaGRAF Workbench communicates with Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x using TCP/IP. This communication protocol provides various file system operations, as well as the uploading of applications. Data is transferred over this protocol unencrypted, which could allow a remote unauthenticated attacker to upload, read, and delete files.
