Never trust user input. Use an "allow-list" approach to ensure that a keyword only contains expected characters (like alphanumeric characters) and reject anything containing keywords like SELECT , FROM , or special symbols like -- and || [5]. 4. Use Web Application Firewalls (WAF)

The string you provided is designed to trick a database into executing a command by appending it to a legitimate search term ( KEYWORD ). It uses the SELECT CASE statement to test if a condition (like 9298=9298 ) is true, which helps an attacker confirm that the database is vulnerable [2, 3]. 2. Primary Defense: Prepared Statements Never trust user input

"SELECT * FROM products WHERE name = ?" (The database treats the input strictly as text, not as executable code) [4, 5]. 3. Implement Input Validation Use Web Application Firewalls (WAF) The string you

It looks like you've included a snippet of code in your query. Specifically, this is a "Boolean-based" or "Error-based" blind injection attempt using Oracle-specific syntax like XMLType and CHR codes to extract information from a database [1, 2].
