Developing a custom gadget chain for PHP deserialization - Lab#09
In this video, I walk through the process of developing a custom gadget chain to exploit an insecure PHP deserialization vulnerability. The application uses a serialization-based session mechanism, and with the right object structure, we can achieve remote code execution (RCE).
Using knowledge of PHP magic methods and object injection, I craft a custom gadget chain that allows me to execute system commands and delete the morale.txt file from Carlos’s home directory.
🔹 Lab Type: Insecure Deserialization (PHP – Custom Gadget Chain)
🔹 Objective: Build custom PHP gadget chain → Achieve RCE → Delete morale.txt
🔹 Focus Topics: PHP magic methods, object injection, custom payload crafting
📌 Great for those wanting to understand PHP internals, object-oriented attack surfaces, and how to build your own gadgets for real-world exploitation.
