## Details
A SQL injection is possible.
The following conditions have to be met for being vulnerable:
- Exim Version 4.98
- Build time option _USE_SQLITE_ is set (it enables the use of SQLite
for the hints databases) -- check the output of `exim -bV`, whether it
contains
```
Hints DB:
Using sqlite3
```
- Runtime config enables ETRN (`acl_smtp_etrn` returns _accept_
(defaults to _deny_))
- Runtime config enforces ETRN serialization (`smtp_etrn_serialize` is
set to _true_ (defaults to _true_))
