how to fix this problem？

BigNerd95 commented 6 years ago

Maybe related to PySquashfsImage Try reinstalling it Or simply download the firmware and extract it using binwalk

I have downloaded the "routeros-x86-6.27.npk",can I unzip to use the "/nova/bin/www" file as the "www_binary"? i don't understand to use binwalk to get which file. And, also I get that error: use mips: Traceback (most recent call last): File "./StackClash_mips.py", line 230, in payload = build_payload(binRop, shellCmd) File "./StackClash_mips.py", line 127, in build_payload stack_finder = binRop.get_gadgets("addiu ?a0, ?sp, 0x18; lw ?ra, 0x???(?sp% jr ?ra;")[0] File "./StackClash_mips.py", line 43, in get_gadgets raise Exception("Cannot find gadgets!")

Any way to extract the file is valid Only check it is an ELF file once extracted

Mips: it looks like it isnt able to find the gadgets, very strange, which version of ROS are you using?

X86: it looks like a pwntools problem, i cant offer support about this

@BigNerd95 thanks.the version is 6.27,my test ip is 180.166.152.83 in fact no one target version I test is succesful......

BigNerd95 commented 6 years ago

I tested it on 6.18, 6.37 and 8.38.3 And it works

Are you sure you are using mipsbe version of www with StackClash_mips?

It can find gadgets for me
