            Is there a way to convert memory adress string to little endian input?
            Asked 2022-Feb-04 at 10:18

            this thing could easily be solves by writing a function that builds the string that I want. But it would be a bit nicer, and a bit more concise if there is something that I can just import and use, it seems lik there should be. I have a python script that uses python pwntools.

            It reads a memory leak from a executable that consists of a string that basically just looks like this:

            i am working on reverse shell project using pwn as Client/Server instead of using socket because it's more comfortable in receiving (recvuntil) messages ,but when ever i tried to convert it to EXE using pyinstaller to onefile it ended up failing , generating a corrupted exe or generate an exe that keeps giving Errors ,i even have tested this program on console first.

            Why hex address addition are not the same in gdb and python
            Asked 2021-Feb-11 at 15:35

            I'm doing a buffer overflow exercice with gdb and python(3.9) pwntools on kali. I'm working with a 32bits ELF so my context is set this way : context(arch="i386", os="linux")

            In my python script : 0xf7e280e0 + 0xefdc8000 = 0x1e7bf00e0

            Can you help me to understand why the result is not the same?

            Python performs arithmetic with arbitrary precision. If you add two 32-bit numbers, the result could overflow and produce a number which does not fit in 32 bits.

            Is there any way to force this?

            Assuming by "force this" you mean: force Python to compute a 32-bit number, sure: you just need to mask off the bits you don't want:

            I think you wrongly calculated some offset. I modified your script to automate some calculation. I am using Ubuntu 20.04 for testing. Btw, you should use %p instead of %llx for address.

            Set breakpoint after printf(input); then inspected the stack, I decided to go for __libc_start_main to leak libc base:

            After searching the instruction movaps segfault I came across this site that explains the issue.

            The MOVAPS issue

            If you're using Ubuntu 18.04 and segfaulting on a movaps instruction in buffered_vfprintf() or do_system() in the 64 bit challenges then ensure the stack is 16 byte aligned before returning to GLIBC functions such as printf() and system(). The version of GLIBC packaged with Ubuntu 18.04 uses movaps instructions to move data onto the stack in some functions. The 64 bit calling convention requires the stack to be 16 byte aligned before a call instruction but this is easily violated during ROP chain execution, causing all further calls from that function to be made with a misaligned stack. movaps triggers a general protection fault when operating on unaligned data, so try padding your ROP chain with an extra ret before returning into a function or return further into a function to skip a push instruction.

            Simply adding a call to a ret gadget before the call to system aligned bytes, and allowed me to pop a shell.

            Pwntools is best supported on 64-bit Ubuntu LTS releases (14.04, 16.04, 18.04, and 20.04). Most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.). Python3 is suggested, but Pwntools still works with Python 2.7. Most of the functionality of pwntools is self-contained and Python-only. You should be able to get running quickly with.
