Select Null,null,null,null,null,null-- Vigj - {keyword}' Union All

: In a Union-Based attack, the injected SELECT statement must have the exact same number of columns as the original statement. Attackers use NULL as a placeholder to discover the correct column count without triggering data type errors.

: This operator combines the results of the original query with a new, malicious query. This allows an attacker to retrieve data from other tables that they weren't supposed to see. : In a Union-Based attack, the injected SELECT

The primary goal of this specific payload is . By successfully executing this command, an attacker confirms that: The application is vulnerable to SQL Injection. The original query retrieves exactly six columns. The backend database supports the UNION operator. This allows an attacker to retrieve data from

SQL Injection occurs when untrusted user input is concatenated directly into a database query, allowing an attacker to manipulate the original command. The original query retrieves exactly six columns

: The single quote ( ' ) is used to "break out" of the intended data field. By closing the string early, the attacker can append their own SQL commands.

: This is a random string (often called a "cache buster" or signature) used by security researchers or automated scanners to identify their specific request in server logs. The Objective of the Attack

Implement strict "allow-lists" for user input to ensure it matches the expected format (e.g., only alphanumeric characters).
