The security landscape has improved significantly since the early days of PHP development. Modern best practices include:
While id parameters are most commonly associated with SQL injection, variations like index.php?page= can lead to vulnerabilities. LFI occurs when an application includes files based on user-supplied input without proper validation.
A single quote. The classic SQL injection test.
The attacker inputs inurl:index.php?id= into Google, often appending specific keywords or country codes (like site:.gov or site:.edu ) to target specific industries or regions.
: Ensure the id is actually a number. If someone sends id=DROP TABLE , your code should reject it instantly.
: A WAF can detect and block malicious requests containing SQL injection payloads.
inurl:index.php?id= site:mil
What (e.g., WordPress, native PHP, Laravel) does your website run on? Do you currently use database abstraction layers like PDO?
