Hi Robert,

If your only reason to migrate is to mitigate an OpenSSL vuln, you can try to
replace the openssl.exe binary and the DLLs used in your currently working
Stunnel version. Since there is no compatibility breaking changes in latest
OpenSSL releases, Stunnel should be able to load it without complaining. I
currently do this with the 1.1.1 branch, and it is working flawlessly so far :)
Can't say for sure for the 3.0.0 branch, but it's worth a try.

You can find up-to-date pre-built binaries here:
http://wiki.overbyte.eu/wiki/index.php/ICS_Download#Download_OpenSSL_Binaries_.2
8required_for_SSL-enabled_components.29

Other options are also listed on the official OpenSSL wiki:
https://wiki.openssl.org/index.php/Binaries

Objet : [stunnel-users] Windows service won't start. ""The Stunnel TLS wrapper

service

is marked as an interactive service."

Window 10 LTCS (1089):
"The Stunnel TLS wrapper service is marked as an interactive service.

However, the

system is configured to not allow interactive services.  This service may not

function

properly."

looks like starting with version 5.61, this above error appears in the System

Event log.

I've given a quick glance at the changes from 5.60 to 5.61 and there a lot of

them.

From the release notes, seems that windows services code might have been

affected:

New features for the Windows platform
- Added client mode allowing authenticated users to view logs, reconfigure and
terminate running stunnel services.
- Added support for multiple GUI and service instances distinguised by the

location of

stunnel.conf.

On GitHub, I also noticed that in the source code for src/ui_win_gui.c the

service is

created as follows:

service=CreateService(scm, SERVICE_NAME, SERVICE_DISPLAY_NAME,
        SERVICE_ALL_ACCESS,
        SERVICE_WIN32_OWN_PROCESS|SERVICE_INTERACTIVE_PROCESS,
        SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, service_path,
        NULL, NULL, TEXT("TCPIP\0"), NULL, NULL);ui_win_gui.c at around line

1622

the SERVICE_INTERACTIVE_PROCESS flag is set

Is this flag necessary? I guess that would be the culprit.

my reason to upgrade is because of the CVE-2022-0778 OpenSSL vulnerability

 anyone has a workaround for this?

Microsoft has fully disabled Interactive Service Detection starting with

Windows 10

Build 1803 and Windows Server 2016 and 2019. So, it looks like that that

Interactive

services are no longer allowed and this can't be circumvented by changing some
registry setting like it seems it was possible before.

thank you
