Title
1E-Exchange-DisplayMessage instruction allows for arbitrary code execution
Summary
The 1E-Exchange-DisplayMessageinstruction that is part of the End-User Interaction product pack available on the 1E Exchange does not properly validate the Caption or Message parameters, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue DELETE the instruction “Show dialogue with caption %Caption% and message %Message%” from the list of instructions in the Settings UI, and replace it with the new instruction 1E-Exchange-ShowNotification instruction available in the updated End-User Interaction product pack. The new instruction should show as “Show %Type% type notification with header %Header% and message %Message%” with a version of 7.1 or above.
