the usage of shodanhq generating the information about vulnerabilities on the host system, because shodanhq can detect which application is used.

database's DVWA SQLMAP extraction

.....

the Sqlinjection and the Blind Sqlinjection

Based Story.
The SQL was used to manage the query of database,

The SQLinjection.
the injection-code techniques that exploits a security vulnerability in a webSite, in order to dump the database content to the attacker, or to manipulate the web application to performs operations on the database.






The Blind SQLinjection
the result of Blind SQLinjection are not visible to the attacker, the display of the vulnerability depens on logical statement that injected into the legitimate SQL Statement to perform sepecific operation to call the page resources.
