"SELECT * FROM products WHERE name = '" + userInput + "'"
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]. "SELECT * FROM products WHERE name = '"
"SELECT * FROM products WHERE name = ?" (The database treats the input strictly as text, not as executable code) [4, 5]. 3. Implement Input Validation not as executable code) [4
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 "SELECT * FROM products WHERE name = '"
A WAF can automatically detect and block common SQL injection patterns (like CHR codes and XMLType calls) before they even reach your server [6].
