Hi, Shameem -

Perhaps the use of the PowerClient feature (added to PB in version 2019 R3) to deploy and execute the PB application would address this issue?

Here is a link to an overview description of what PowerClient provides:

    https://docs.appeon.com/pb2019r3/whats_new/PowerClient.html

The following link describes working with PowerClient project using PB 2022 R2:

Best regards, John

Hi John;

Since PowerClient and PowerServer App's are installed & run *locally* along with the PB runtime DLLs, these options will not change all these PBXxxxxx.dll's being read by the PB runtime. The only difference is that the App & the PB runtime are deployed via a Web Server vs an installer (ie: like InstallSheild).

Regards .. Chris

Hi  SHAMEEM;

  I am not sure what the issue is as Appeon has always signed all of it's PB runtime DLLs.

But, they said this kind of problems are seen in any application, it should not be sold in the market and government will ban directly.

Chris,

IMHO.

The issue pointed out in the report is that if a signed DLL is replaced by an un-signed vulnerable program, how to detect and prevent its execution.

Shall a self-contained exe (with runtime(s)) do the trick?
