The CHAR functions are used to bypass simple text filters. They translate to specific letters (like q , b , v ) to create a "fingerprint" or marker in the database response.
It asks the database to check if the number 7365 is equal to a value it generates. The CHAR functions are used to bypass simple text filters
The CASE WHEN (7365=7365) is a "True/False" test. Since it’s true, it returns CHAR(49) (the number 1). If the database processes this and returns a "1" or a success message, the person running the code knows the site is vulnerable. The CASE WHEN (7365=7365) is a "True/False" test
In plain English, this specific string is designed to test if a database is vulnerable by forcing it to perform a logical operation and return a specific result. In plain English, this specific string is designed
The AND ('aRMv'='aRMv at the end is used to balance out the remaining syntax of the original query so the site doesn't crash or show a standard error.
