ps5-payload-gdbsrv

This is a simple GDB server that can be executed on a Playstation 5 that has been jailbroken via the BD-J or the webkit entry points. The server accepts connections on port 2159, and has been tested with gdb-15.

Quick-start

To deploy ps5-payload-gdbsrv, first launch the ps5-payload-elfldr, then load the payload by issuing the following commands:

john@localhost:~$ export PS5_HOST=ps5
john@localhost:~$ wget -q -O - https://github.com/ps5-payload-dev/gdbsrv/releases/latest/download/Payload.zip | gunzip -c -d | nc -q0 $PS5_HOST 9021

Next, launch a new terminal and debug you payload by running the following set of commands:

john@localhost:ps5-payload-dev/gdbsrv$ export PS5_PAYLOAD_SDK=/opt/ps5-payload-sdk
john@localhost:ps5-payload-dev/gdbsrv$ export PS5_HOST=ps5
john@localhost:ps5-payload-dev/gdbsrv$ cd sample
john@localhost:ps5-payload-dev/gdbsrv/sample$ make test

Known issues

  • Symbols from dynamic sony libraries are not loaded correctly at the moment.
  • A couble of arguments passed to the ELF is allocated on the heap, so gdb may report errors when trying to resolve the arguments to _start()
