.NET serialiception

agix · SCRT

Investigates .NET BinaryFormatter deserialization reachable through web inputs and unsigned ViewState. Besides DataSet XXE, it develops a chain through COM unmarshalling, bitmap heap spraying and ROP to execute code in an IIS lab. A JSON converter supports stream inspection and editing; shared object references amplify the spray without duplicating each bitmap in the input.
