A new exploit in the PS3 System Software has been found. The new exploit makes use of a vulnerability in the XMB theme feature, allowing a price of code to be executed after a theme has been installed. The PS3 theme file is able to load the loadme.fu script from any USB port.
The code works on any current firmware version supporting XMB themes (Firmware 1.90+) and does not require any hardware modifications to be made on the device.
How the exploit works:
- Install loader.p3t like a common theme file.
- Put loadme.fu on an USB stick’s root dir.
- Insert USB device into any PS3 USB port.
- Enable the theme you just installed before.
- Hello World.
