The 1E-Exchange-URLResponseTime instruction that is part of the Network product pack available on the 1E Exchange does not properly validate the input parameter, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions.
To remediate this issue download the updated Network product pack from the 1E Exchange and update the 1E-Exchange-URLResponseTime instruction to v20.1by uploading it through the 1E Platform instruction upload UI.
