From my experience - you will not make it since you will have to go through additional security again and passport control for your international flight. The absolute minimum I ever made it in was 40 minutes and that was with SKIPPING lines and RUNNING like crazy through the airport. (In my experience in those cases my suitcases didn't make it anyways)
So you should reach out to your airline (now or at the airport that day) and they will (should !!!) book you on a different flight. You could also do that in Vienna when you actually miss your flight (have done that before), but I recommend getting it done before because it will be less stressful for you! Hope that helped! :)
P.S. As of my knowledge; airlines are required to re-book you and give you at least 1 hour to change flights.

If it's a Schengen connection, you're probably fine if there are no delays to the incoming flight.
Nevertheless, if you do miss it, just go to the airline desk and they'll rebook you on the next connection.

You may be okay: Vienna states a minimum connection time of 25 minutes for some connections. See https://www.viennaairport.com/en/passengers/arrival__departure/transfer
The fact that the airline booked you on one ticket is encouraging: it's a legal connection. Rebooking a passenger and/or having to put them in a hotel is expensive for the airlines. If that happens frequently they would increase the connection time and stop selling this type of ticket. Keep in mind that actual schedules are often padded: makes their on-time record look better and reduces delay penalties. A flight where all goes "as planned" arrives significantly earlier than scheduled.
This being said: everything needs to go "as planned" and any delay or hiccup will throw you off.
