Remote Lua Loader : Mastering PS4 And PS5 Exploits With Advanced Scripting

The Remote Lua Loader is a tool designed to exploit vulnerabilities in games built with the Artemis game engine, which utilizes Lua scripting.

This exploit allows users to load arbitrary Lua files onto their PS4 or PS5 consoles, potentially paving the way for future kernel exploits.

Key Features

• Firmware Independence: The loader is not dependent on specific firmware versions, making it versatile across different console updates.
• Supported Games: It currently supports several games, including Raspberry Cube, Aibeya, Hamidashi Creative, Hamidashi Creative Demo, Aikagi Kimi to Issho ni Pack, and Aikagi 2.
• Network Capability: Users can send Lua scripts over the network to be executed on the console, enhancing its utility for remote operations.
• Exploit Mechanism: The exploit works by modifying save files in supported games. When the game boots, it loads a custom save file, which in turn loads a Lua script, allowing for arbitrary code execution.

To set up the Remote Lua Loader, users need to follow the instructions provided in the SETUP.md file within the GitHub repository.

This involves preparing a modified save file for one of the supported games and using it to load the Lua loader. Once set up, users can send Lua scripts to the console via the network, which will execute them upon launch.

The development of the Remote Lua Loader has been a collaborative effort, with contributions from several community members:

• Gezine: Initially discovered the vulnerability and shared the concept.
• Flatz: Contributed ideas and Lua implementations.
• Null_ptr: Assisted with testing and ideas.
• Specter & Chendo: Provided insights from their webkit implementations.
• Al-azif: Shared parts of his SDK and FTP server information.

While the Remote Lua Loader currently allows for the execution of simple Lua scripts, its potential lies in its ability to serve as an entry point for more complex exploits, including kernel-level exploits.

This could significantly enhance the capabilities of PS4 and PS5 modding communities in the future.
