SQL Injection - Stacked Queries Scanner
Tests for stacked query SQL injection allowing multiple statement execution.
What is SQL Injection - Stacked Queries?
Stacked queries SQL injection allows attackers to execute multiple SQL statements in a single query by using the semicolon separator. Unlike other SQL injection types that modify existing queries, stacked queries let attackers execute entirely new statements including INSERT, UPDATE, DELETE, or even administrative commands.
Why is This Important?
This is the most dangerous form of SQL injection because attackers can modify or delete data, create admin accounts, drop tables, or execute system commands. It enables complete database takeover and potential operating system access through features like xp_cmdshell.
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.
Key Capabilities
Industry-leading web security testing powered by AI, trusted by security teams worldwide for accurate vulnerability detection.
- Deep web crawling with JavaScript rendering support
- Context-aware payload generation for each parameter
- False positive elimination through response analysis
- OWASP Top 10 and CWE compliance mapping
- Seamless CI/CD and DevSecOps integration
Frequently Asked Questions
Which databases support stacked queries?
SQL Server and PostgreSQL support stacked queries by default. MySQL supports them only with specific APIs (mysqli_multi_query). Oracle doesn't support them in most contexts.
What's the worst case scenario?
Attackers can create admin users, modify financial records, delete all data, or use database features like xp_cmdshell (SQL Server) to execute operating system commands.
Why are stacked queries more dangerous than UNION?
UNION can only read data. Stacked queries can write, delete, modify data, and potentially compromise the entire server through command execution.
How do I test if my app is vulnerable?
Inject a semicolon followed by a benign statement like SELECT 1. If no error occurs and the page behaves normally, stacked queries may be possible.
