Hi Andrew,
You are correct. I have setup a test network with the fake-mail-server
running in a VM and I am liaising with the SecVuln guys at the moment to
see if I can reproduce the test they say shows the vulnerability when
Exim is sending email.
Best wishes,
Harry

Hi Jeremy,
Thanks for the swift reply. Here is the (anonymised) output of the
test tool for reference. It looks like exim 4.94.2 (Centos 8) is not
vulnerable:
python3 ./command-injection-tester --smtp <MAILSERVER>
As I understand https://nostarttls.secvuln.info/
command-injection-tester only tests for bugs when exim is receiving
email;
to test for the *response* injection bugs in CVE-2021-38371, when exim
is sending email, you need to use
https://github.com/Email-Analysis-Toolkit/fake-mail-server
which looks more involved to me.
