1. Vendor Description:

AcySMS is a component which enables you to send follow-up campaigns,
auto-responders, newsletters, promotions, special offers, automated
messages... via SMS/Text Messages.

2. Technical Description:

CSV Injection (aka Excel Macro Injection or Formula Injection) exists in
the export feature in the Acyba AcySMS extension before 3.5.1 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 AcySMS Component.
