The developer known as goakal-play has built a custom version of a host server for the umtx2 exploit , intended to run on STB (Set-Top Box) devices or Armbian-based operating systems, with the intent of jailbreaking the PlayStation 5 in local or offline environments.

The umtx2 exploit , at the core of the project, exploits the CVE-2024-43102 vulnerability in the console WebKit to gain access to the kernel and allow the execution of unsigned code, such as homebrew payloads or debugging tools.

Unlike the original idlesauce repository , which focused on using the exploit via PS5 browsers or sites hosted on Cloudflare, this implementation is optimized for alternative server environments, such as embedded devices or single-board computers, including the Raspberry Pi .

The goal is to provide a self-contained, internet-independent solution that is useful for those who want a permanent or private setup.

The server is probably inspired by the umtx2host.py file , but has been properly adapted for the STB/Armbian device architecture.

It includes a local HTTP script that can deliver the exploit to the console, along with an ELF loader running on dedicated ports (such as 9020), which is needed to send payloads to the PS5.

Characteristics

Automatically start the server at boot via systemd.
DNS Spoofing and Rebind Attack Management .
HTTP support for the esphost app and HTTPS for redirecting from the PS5 user guide menu.
Lightweight and optimized for STB devices.

Note: This project requires the STB (Set-Top Box) device to be rooted first. After rooting, you need to properly install Armbian before proceeding with the configuration .

Configuration

Installing dependencies

sudo apt update
sudo apt install dnsmasq hostapd net-tools -y
