Turn the water off, and remove it. Those things are rubbish, and always leak eventually.
If you need a valve there, cut out the damaged section of pipe, and install a proper tee and valve. If you don't need it, cut out the damaged section of pipe and install a coupling.
If you're not an expert solderer, They make push-fit fittings (SharkBite® is the well known brand) that are easy to work with. These fittings are more expensive than typical fittings, but ease of use and not having to buy soldering supplies might make them comparable.
It is Grohe model 29733
How I found it...
After weeks of searching, I stumbled on a picture of a diverter handle that has the same icons for shower and hand-held positions that my handle has (see the third picture in the original question). Knowing that the handle in that picture was made by Grohe, I started searching Grohe's website and found an almost identical diverter (based on the parts I can see). The only thing that is different is the length of the knurled part of the stem.

This looks like you have a Single Valve Control Shower .. where yours has temperature settings on it. Maybe this is your tempering valve, it can also be a Pressure Balance Valve or what sometimes can be referred to as anti-scalding valves these valves prevent burns from water when say the toilet is flushed - all the cold water flows to the toilet and that leaves only hot for the shower hence you get scorched.
More and better pictures will be needed if you want to know brand and model information.
BTW - the valve in the back might be part of the assembly and actually have the manufacturer model or info on it.
