Compiling problem

[tomservo84]

I'm trying to compile your jb from source on a Linux server. I've got python 3.7.5, ROPgadget v6.3, my PS4 is running 6.72.

When trying to work with the gadgets.txt file, I get the following error:

8cc/8cc/python/rop-ps4-8cc /dev/stdout 8cc/librop/.c printf_stub.c 8cc/ps4/.c oldkex.c | python3 8cc/bad_hoist/rop/compiler.py /dev/stdin 8cc/bad_hoist/dumps/gadgets.txt > build/oldjb/c-code.js

raise SyntaxError(i)
SyntaxError: mov [rax], rdi
make: *** [Makefile:13: build/oldjb/c-code.js] Error 1

I've uploaded my gadgets.txt file here:

I'm not sure if I'm missing something, maybe a python library?

Probably your library dumps are truncated. My gadgets.txt has 1058518 lines, while yours only has 93079 lines. Make sure you have a non-faulty network connection.

For reference: my webkit.bin is 26259455 bytes long, and the mov [rax], rdi gadget is at webkit_base+0xdcaa77.

Wow...yes...something is definitely not right. My webkit.bin is 278,527...1% of the proper size. I can't tonight but I will try again tomorrow...and instead of using the wifi I will try wired.

[tomservo84]

That was it! I hooked up to wired connection, and all worked as it was supposed to. I just never realized that the size of those files was too small.

Thanks so much!

AFAIK you could've closed this yourself.
