Insecure Deserialization Scanner
Tests for unsafe deserialization leading to remote code execution.
What is Insecure Deserialization?
Insecure deserialization occurs when applications deserialize untrusted data without validation. Attackers can craft malicious serialized objects that execute code when deserialized. This affects Java, PHP, Python, Ruby, .NET, and any platform using serialization.
Why is This Important?
Deserialization vulnerabilities often lead directly to Remote Code Execution (RCE). Attackers can execute arbitrary commands, gain full server control, and pivot to other systems. Many critical breaches have exploited deserialization flaws.
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.

Frequently Asked Questions
What are deserialization gadgets?
Gadgets are classes in the application's classpath that can be chained together during deserialization to achieve code execution. Tools like ysoserial generate payloads using known gadget chains.
Where is serialized data found?
Cookies (especially base64-encoded), hidden form fields, session storage, ViewState (ASP.NET), message queues, and any inter-service communication using native serialization.
Which serialization formats are vulnerable?
Native Java serialization, PHP serialize(), Python pickle, Ruby Marshal, and .NET BinaryFormatter are high risk. JSON and XML are safer but can still have issues.
How do I prevent deserialization attacks?
Avoid native serialization for untrusted data, use safe formats like JSON, implement integrity checks (signatures), and use allow-lists for deserializable classes.
