insecure-deserialization

What problem does it solve?

This Skill addresses the critical security vulnerability of insecure deserialization, which can lead to Remote Code Execution (RCE) and other system compromises. It provides a comprehensive methodology to identify, exploit, and mitigate these risks.

Core Features & Use Cases

• Vulnerability Identification: Detects insecure deserialization sinks and recognizes serialized data formats across various languages (Java, PHP, .NET, Python, Node.js, Go, Rust, Ruby).
• Exploitation Guidance: Offers techniques for bypassing filters, using gadget chains (e.g., ysoserial), and exploiting language-specific quirks.
• Modern Attack Vectors: Covers exploitation in containerized environments, message queues, serverless functions, CI/CD pipelines, and APIs.
• Use Case: When testing a web application that accepts serialized objects in cookies or API requests, use this Skill to systematically identify and exploit potential deserialization vulnerabilities.

Quick Start

Use the insecure-deserialization skill to identify potential deserialization sinks in the provided Java source code.
