Overview

The SQL Injection Detector helps you identify potential SQL injection patterns and malicious database payloads within raw text, log entries, or application inputs. By scanning your text against common SQL injection signatures, it highlights vulnerabilities before they can compromise your database security.

When to use

When reviewing application logs or HTTP request payloads for suspicious database query patterns.
When testing user input fields and API endpoints during security audits or vulnerability assessments.
When validating raw text inputs before processing them in database queries to ensure they do not contain SQL commands.

How it works

1Paste the text, query, or log data you want to analyze into the input text area.
2Select your preferred scan mode, choosing between a Quick Scan for common patterns or a Full Scan for deeper heuristic analysis.
3Click the analyze button to run the detector and view the identified SQL injection signatures and risk levels.

Use cases

Analyzing web application firewall (WAF) logs to investigate potential SQL injection attempts.
Sanity checking user-submitted form data during manual penetration testing.
Educating developers on what SQL injection payloads look like by analyzing sample inputs.

Examples

1. Analyzing Suspicious Login Input

Security Analyst

Background

An analyst notices an unusual login attempt in the application logs that bypassed standard validation.

Problem

Verify if the input string contains a classic SQL injection bypass attempt.

How to use

Paste the suspicious input string `' OR '1'='1` into the input text area and select 'Quick Scan'.

Scan Mode: Quick Scan

Outcome

The tool flags the input as a high-risk SQL injection pattern due to the presence of the tautology `' OR '1'='1`.

2. Reviewing API Payload for Blind SQL Injection

QA Engineer

Background

A QA engineer is testing a search API endpoint and wants to check if a specific payload contains time-based blind SQL injection patterns.

Problem

Detect subtle SQL injection signatures like sleep commands or database version queries.

How to use

Paste the payload `1; SELECT PG_SLEEP(5)--` into the text area and select 'Full Scan' for a comprehensive check.

FAQ

What is the difference between Quick Scan and Full Scan?

Quick Scan checks for common SQL injection keywords and basic patterns, while Full Scan performs a deeper analysis including complex logical operators and encoding tricks.

Does this tool execute queries on my database?

No, this tool only performs static text analysis to detect patterns and does not connect to or interact with any database.

Can this tool detect all types of SQL injection?

It detects common patterns like tautologies, union-based, and piggybacked queries, but should be used alongside dynamic application security testing.

Is my input text stored or shared?

No, your input text is processed locally or in-memory to perform the scan and is not saved or shared.

Can I scan entire log files?

Yes, you can paste log snippets or raw text payloads directly into the input field to scan them for SQL injection signatures.
