Affected Versions =============================================================================================================================================
| # Title : RustFly v2.0.0 - Event Manipulation |

| # Tested on : windows 11 Fr(Pro) / browser : Mozilla firefox 145.0.2 (64 bits) |
| # Vendor : https://bixat.dev/products/rustfly |
=============================================================================================================================================

[+] Summary : The remote UI control mechanism of RustFly accepts raw hex-encoded instructions over UDP. Some sequences trigger execution of remote
system-level operations. Improper sanitization allows command-level injection.

Steps To Reproduce:
-------------------
1) Configure IP and port of RustFly target.
2) Run this PHP PoC sender script.
3) Observe behavior change / message processing by RustFly.

=========================================================
PoC Impact:
-----------
* Proof of input injection capability
* Demonstrates command-carrier transport
* No shell-spawning payloads included (safe demonstration)

=========================================================
Instructions:
-------------
Save file as:
poc.php

Run:
php poc.php
