web-deserialization

Testing insecure deserialization involves identifying serialized data in cookies or parameters, generating payloads using tools like ysoserial.net or phpggc, and verifying execution via out-of-band callbacks. It supports Java, PHP, .NET, Python, and Ruby platforms.

A deserialization gadget chain is a sequence of application classes and methods exploited to execute arbitrary code when untrusted serialized data is deserialized. Mapping these chains helps assess remote code execution risks in target frameworks and classpaths.

Yes, you can generate and deliver serialization payloads to common entry points including API bodies, cookies, and web parameters. Tools like ysoserial.net, phpggc, and marshalsec help craft payloads, while callback infrastructure verifies successful exploitation.

Yes, this deserialization assessment works with JSON and XML payloads alongside Java, PHP, .NET, Python, and Ruby. It detects weaknesses in APIs and web applications where serialized data flows through parameters, enabling gadget chain mapping and payload generation.

You need tools such as ysoserial.net, phpggc, GadgetProbe, and marshalsec to map gadget chains and generate payloads. Additionally, callback infrastructure is required to deliver payloads and verify out-of-band execution outcomes.

To mitigate insecure deserialization risks, you should apply defense-oriented recommendations specific to your language and framework. This includes avoiding native deserialization of untrusted data and implementing safe alternative parsing methods.
