PS5 ELF Loader

This is a BD-J Xlet that starts a socket server on port 9020, that reads and executes ELF files transerved over TCP. The Xlet relies on a privilege escalation vulnerability discovered by theflow, which was later reproduced for the PS4 by sleirsgoevy. To escape the Java sandbox, the Xlet uses that vulnerability to disable the security manager using a technique discovered by sleirsgoevy. Once we are out of the sandbox, we can start a socket server that implements an ELF loader. To launch ELF files remotely, you may use netcat:

john@localhost:~/bdj-sdk/samples/ps5-elf-loader$ make -C payloads
john@localhost:~/bdj-sdk/samples/ps5-elf-loader$ nc -q0 ps5 9020 < payloads/getpid.elf
