ps4jb

This is a full chain exploit for PS4 firmware 6.72. Basically this is TheFlow's POC together with PS4-specific kROP & kernel patches. Mira is used as a HEN payload.

Building from source

To build from source, clone this repository recursively, and run these commands:

cd src
make

You will get a fresh copy of the binary build in src/build/.

Dependencies: python3, gcc, ROPgadget. Note: Mira is not being built from source

Adding your own payloads

miraldr.c loads 65536 bytes at address stored in JS variable mira_blob into RWX memory and jumps to it. At this point only the minimal patches (amd64_syscall, mmap, mprotect, kexec) are applied (i.e. the process is still "sandboxed"). Normally mira_blob contains MiraLoader.

mira_blob_2_len bytes at mira_blob_2 are sent to 127.0.0.1:9021 in a background thread. If mira_blob contains MiraLoader this will be run in the same way but with the full patchset applied & already jailbroken.
