IE Proxy Settings are getting out from sandbox [SOLVED Beta 5.21.4]

Post by gjf » Fri Aug 11, 2017 2:47 pm

Hi All.

OS: Windows 10 Pro x64

I am observing a strange behaviour of IE proxy settings when running in sandbox. From time to time this settings are getting active in unsandboxed IE also. Disabling it in unsandboxed IE leads to disabling it in sandboxed IE (and it's normal), so I have to re-enable it - and after some time (not instantly) I can observe enabled proxy in unsandboxed IE.

Why this registry parameter "leaks" from sandbox? Taking into account IE proxy setting is a system proxy setting it is very annoying.

Also I wonder why it is not possible to set the sandbox in Sandboxie to direct all traffic through preset proxy.

Hello gjf,

Thanks for the report. We are aware of the scenario. It seems to be generated by a service that Sandboxie talks to, which is writing to a specific registry location if you are using proxies (\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\iphlpsvc\Parameters\ProxyMgr\{E2769C86-1E8F-473D-B3FD-5A8906FB814A})
You may see something like http://whatever/autoconfig/localproxy.pac under the autoconfigURL entry in the registry.

The devs are looking for a way to prevent this without breaking proxies.
We will provide an update once it becomes available.

Regards,
Barb.-

This is still under investigation, so this information may be updated later on.

I still believe the best way is to add some parameter for sandbox to allow forward all traffic through proxy. In this way it is not necessary to change parameters of browsers at all.

But it's up to devs of course.
