I have an app that normal users need to be able to run, but requires administrator privileges to actually function.
I tried to make the shortcut that my users run it with “Run as administrator” but this just causes a UAC prompt whenever they try to run the app.
Is there any way to elevate privileges programatically, without my users needing to go through a UAC prompt and/or knowing an administrator password? From a security standpoint, I understand that most applications shouldn’t be allowed to do this, so I’m hoping there is some way to do it if I can provide a valid username/password pair, or something.
The app is written in C#, so a fully managed solution would be preferred, but p/Invoke Black Magic (or even writing an MC++ Wrapper Which We Do Not Speak About) would be more acceptable than disabling UAC entirely.
Generally this problem solved by installing a Windows Service which runs as SYSTEM or an admin account. Then your application can request the privileged action from this service.
Obviously to not pose a security threat ensure that your service can’t run arbitrary code or something which might leave the all users vulnerable to privilege escalation attacks.
Winpcap and most of the other sniffing applications use a similar design to give sniffing access to unprivileged users.
