CVE: CVE-2022-40347

Riferimenti:

1. Descrizione:

Intern Record System 1.0 consente SQL Injection tramite i parametri 'phone', 'email', 'deptType' e 'name' in "/intern/controller.php". Lo sfruttamento di questo problema potrebbe consentire a un attaccante di compromettere l'applicazione, accedere o modificare i dati o sfruttare le vulnerabilità più recenti nel database sottostante.

2. Proof of Concept:

In sqlmap usare il parametro 'phone', 'email', 'deptType' o 'name' per eseguire il dump del database 'department'.
Quindi eseguire SQLmap per estrarre i dati dal database:
