Just heat the nozzle to about 120C in the menu on the printer. Open the door and clean with a tissue or paper towel.
More importantly - this is called a "head flood" and you got the most mild version ever but it can be a disaster. It's never happened to me but it happens a lot - especially to people who have printed fewer than 100 prints.
The fix is to get your parts to stick better to the bed. Ultimaker has much advice on this. I have a whole video on this on youtube. The main tricks: squish, temperature, brim, rounded corners, glue. I talk about each of these for many minutes as they are complicated and it's good to understand.
squish, temp, brim are set by the ABS profile by default. Don't skip brim if your parts aren't sticking (I don't use brim except very rarely for the most difficult of prints). So if you haven't messed with profiles you probably just need to worry about the last issue, glue. I recommend Magigoo. They have a product specifically for ABS. Get that. It will save you major headache (no head flood).
If you have 20 minutes, this video will teach you a lot:
Thank you both for your help! I tried first heating it up and it went off in one piece, so it wasn't necessary to use acetone; I imagine it can be helpful in more severe cases.
Anyway, I realised that the Print Core 1, where it all happened, doesn't fit with the silicone cover so good as in the Print Core 2, as number 2 is a little bit lower than the first. That said, I imagine it's easier to have head flooding in the first one rather than in the second. So, do you know if there is any other option to protect better the first printcore? Like a tighter silicone nozzle cover?
Thank you again,
PS: kudos for your video gr5! Nice to see and very helpful!

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

we had one of these and used acetone to soften the abs and removed it with pliers.
Nozzle still works like a charm, but use a small brush of paper towels to apply the acetone
