This repository contains a Java exploit targeting deserialization vulnerabilities. The main entry point is 'src/TestDeserialize.java', which orchestrates a multi-threaded attack to manipulate Java object serialization and memory layout. The exploit constructs a serialized object graph that, when deserialized, disables the Java SecurityManager and executes an arbitrary system command (in this case, launching the calculator via 'Runtime.getRuntime().exec("calc")'). The code leverages custom Serializable classes (BigClass, Class1, Class2, MyClass) with overridden 'writeObject' methods to control the serialization process and timing. The exploit uses Java's Statement and AccessControlContext objects to escalate privileges by injecting an AllPermission ProtectionDomain. The attack is performed entirely in Java and does not require network access, but it assumes the attacker can supply serialized data to a vulnerable Java application. A fingerprintable endpoint is the use of the 'file:///' URL in the CodeSource for the ProtectionDomain, which may be used to identify similar exploits or payloads. The repository is structured as a proof-of-concept exploit for Java deserialization vulnerabilities, demonstrating both memory manipulation and privilege escalation leading to arbitrary code execution.
