1. Vendor Description:

AcyMailing is a reliable Newsletter and email marketing extension for
Joomla.
It enables you to efficiently manage an unlimited number of subscribers,
organize them into mailing lists, send personalized newsletters (Hi
{name}...)

2. Technical Description:

CSV Injection (aka Excel Macro Injection or Formula Injection) exists in
the export feature in the Acyba AcyMailing extension before 5.9.6 for
Joomla! via a value that is mishandled in a CSV export.

3. Proof Of Concept:

Login as low privileged user who is having access to Acymailing Component.
Rename user name as @SUM(1+1)*cmd|' /C calc'!A0.

When high privileged user logged in and exported user data then the CSV
Formula gets executed and calculator will get popped in his machine.

4. Solution:

Upgrade to version 5.9.6
