Furthermore, if the AutoBuild functionality is not used on the GR Node, the AutoBuild service can be disabled on the GR Node as an alternative mitigation that does not require patching.\n\nAVEVA recommends users who need to continually use the AutoBuild functionality and cannot disable it in System Platform Versions 2017 through 2020 R2 P01 (inclusive) are affected by the vulnerabilities and should first upgrade to one of the System Platform versions listed below, then apply the corresponding security update:\n    System Platform 2020 R2 P01, 2020 R2, 2020: Apply AVEVA Communication Drivers Pack 2020 R2.1\n    System Platform 2017 U3 SP1 P01: \n\nFirst apply AVEVA Communication Drivers Pack 2020 R2  AVEVA notes that Activated Licensing is required to apply AVEVA Communication Drivers Pack 2020 R2 on top of System Platform 2017 U3 SP1 P01. For information on AVEVA license compatibility, please contact AVEVA Customer Support.\nThen apply AVEVA Communication Drivers Pack 2020 R2.1\n\nPlease see AVEVA\u2019s security bulletin AVEVA-2021-002 for more information."
