Whitelist custom extensions in 6.5+

shawnkhall 3 years ago updated by Benjamin 6 months ago 15

Background: Control 6.5 imposes a signature validation scheme to ensure the integrity of the Connect install (per this post). This is a net good for most of the community base. For the rest of us it's more trouble than it's worth.

Request: We need the ability to either whitelist custom extensions from validation or disable the signature validation scheme entirely.

Reasoning: I've developed quite a few extensions in an on-premise Control installation to automate significant portions of my business. I'm not willing to share some of this code since it exposes the inner workings of my business, sometimes usernames and passwords, trigger URLs, and plenty of other information that would be useless for the rest of the world, but could increase the risk of my own business data should it be shared with a third party -- even ConnectWise. Microsoft, Google and Adobe have each been hacked in the past, so it's safe to assume that anything I share with CW will eventually be exposed as well.

The hosted developer instance option requires me to share business logic and requires significant rewrites to the code for each of my extensions to be able to prevent business information exposure. Furthermore, as far as I can tell, some of the functionality can not be rewritten in a way that prevents this exposure.

I've submitted an extension to CW in the past and it took weeks to have it approved. It took weeks to be approved for a developer instance. I can only imagine initial approval of each of my extensions to be able to use them in my own on-premise install will take weeks as well, and even minor updates to my extension (such as cosmetic changes or field formatting) will likely take weeks to be approved as well. 

On-premise users require the ability to continue to use and develop our extensions without exposure to ConnectWise. Please enable us to whitelist our custom extensions within the web.config so we can maintain the integrity of our own installations and source code.

Available in Version:

ConnectWise's silence on this issue is deafening.  I have yet to see one single logical reason put forth on why it is beneficial for customers that ConnectWise must review and approve private extensions that can only run in a private on-premise install.  Of course it makes sense for public extensions and for cloud-hosted deployments, but not for private extensions.  Please listen to your on-premise customers, especially those that you obtained through buying ScreenConnect.


I used to use the Guest Session Starter Exe extension, by Elsinore Support (Remember them?). This enables a guest to download a very small exe (suitable for placing on the desktop), which would initiate a Guest Session on demand.  Now depreciated, Quick Support SOS is supposed to do similar.  However I was able to customise the exe file to carry my brand & logo, and now due to "signature violation", this crucial feature has been "outlawed". 

My brand and logo tells MY customers that it's ME at the other end of the remote support connection & not some scammer.

I have had to clean up after one client was actually scammed by some from "Microsoft" who used a ScreenConnect client.  That's why I put MY logo on ScreenConnect.

Preventing me from doing so is interfering with my business.  Branding customisation was the key reason why I chose ScreenConnect over other Remote Support packages.  I host my own on-premise install & pay my renewal licences.  You should not break things that worked perfectly before. And when you do, you MUST put them right quickly.

FAB-ITRescue, we have registered your request to customize the SOS deployer. In the meantime, you can submit your version of GSSE and we will get it signed for you. You can also sign up for a developer instance here: https://docs.google.com/forms/d/1xIku2r1fZgX5VlxXUNih_u6l25-vATYBwU9CxX1GOSE/edit. Thank you.


I agree with Davidson. There is NO good reason to prevent someone from using unsigned extensions ON THEIR OWN SERVER. This is functionality which has been a part of the tool for a very long time, and allowed many of us to incorporate the tool tightly into our businesses. Now that this functionality has been locked out, we are prevented from upgrading and receiving security fixes or new features, or getting resolutions to bugs in the software. You are incentivizing your customers to look at your competitors. 

We have already chosen NOT to purchase another ConnectWise product due in part to this decision (you were eliminated from consideration for a new ticketing tool for our customer support department).

Considering for Future Release

Do you have a potential ETA for future release? My ConnectWise Control renewal is due soon and getting this feature back is the deciding factor.

Any news on this feature request?


I would like to also add that we will be stopping support and switching to a different solution if this doesn't get resolved soon.


Any update on this? Roadmapped?


As an example of just how ridiculous reliance on a third-party resource is (such as ConnectWise signing our extensions), ConnectWise even removed the page from their site that said they were removing this ability. 


Connectwise - this is awful. I have been paying to renew every year but hadn't upgraded for a while (my fault, but, no good reason to). Due to the disclosed vulnerability I had to upgrade and now basic functionality - WHICH THE SOLUTION WAS SOLD ON no longer works. I'm sorry, but, going via you for a cosmetic change and waiting weeks is simply not suitable., nor is sharing internal code.

I agree with everything shawnkhall said above.

To remind people, this was the selling point:

from 2017

When I bought it:


I submitted one of my extensions almost FOUR MONTHS ago to the "approval process" and it has yet to be approved by ConnectWise. As far as I'm concerned this is breach of contract. 

Hi Shawn, 

Sorry for the delay in extension review. I'll follow up with the team today and see if I can get that pushed through. 

The ConnectWise Control team was recently restructured, leaving some extension reviews in an unknown status.




It's been well over 2 years now, and still no change. The message is clear - "Find another solution, ConnectWise does not care, and does not want your business."


I completely agree. I went with connectwise several years ago for the customization labtech and screenconnect offered. Now they keep taking features away and making the product worse. I can't ever get any real support out of them anymore when something breaks either. Endless ticket blackholes and basically told that is just how it is and maybe they will fix it someday. Really sad to see a tech company go this way.
