I'm currently working on the following CTF exercise (x64 version), where the objective is to overwrite a pointer stored on the heap to control the write address of strcpy(): https://exploit.educat. Education. I didn't find any write-ups for the new Phoenix VM of exploit.education, so I decided to publish my own notes. Phoenix Phoenix introduces basic memory corruption issues such as buffer overflows, format strings and heap exploitation under "old-style" Linux system that does not have any form of modern exploit mitigation systems enabled. Phoenix 4 - Net srie Net - zero. The calls to strcpy are not bounds-checked and therefore prone to a heap-based buffer overflow. No License, Build available.

This first level is intended to show what can happen in memory when data is read into a buffer without checking if the input data will fit into the buffer. Don't feel like you have to write your own shellcode just yet - there's plenty on the internet. This code allocates two memory chunks and stores them in d and f so f is after d in the heap, then it uses strcpy to copy argv[1] to d->name but with out size checking, a classic overflow.

So lets use format string vulnerability here, To control the buffer space better, lets use %x (hex) If we pass %32x it pops 32 hex values from stack. Rebranding and rebuilding infrastructure, should take a few weeks. Linux For Linux open terminal, it's as easy as: sudo apt update sudo apt install qemu sudo apt install qemu-system Check it's address in memory, it can't be just 0x1179 Once installed, just right-click on the downloaded Phoenix image file & select "Extract Here." /* * phoenix/stack-three, by https://exploit.education * Stack Five. Phoenix v1.0.0 alpha 3 Latest Jan 16 . So we have to enter: (shellcode + junk to fill the buffer + 8 bytes for RBP + RIP with the address of the buffer). When dealing with shellcode it's a good idea to unset some environment variables that gdb adds them to jump to the right address. Exploit Education Phoenix Stack Overflowshttps://exploit.education/phoenix/https://www.infosec-ninjas.com/ Format-Two. Though this one is a little trickier. Thus, we can overflow the buffer variable by providing input longer than 128 bytes. . exploit.education, Phoenix This is the third of the binary exploitation challenges of the Phoenix series from exploit.education.

This was possible because the function that reads the input from the user, does not validate the input. Phoenix is the next progression from Nebula. ./boot-exploit-education-phoenix-amd64.sh Now that the image is running, you can SSH to the machine with "user" as the both the username & password: ssh -p2222 user@localhost Windows You can use WinRAR to extract the downloaded file. The description and source code can be found here: https://exploit.education/phoenix/stack-four/ For this program, we'll need to overwrite the return address saved on the stack from calling the start_level () function to redirect the flow of execution to the complete_level () function: void complete_level () { I tried these 2 scripts to set up phoenix from Exploit-Education but faced the below errors could not find any . This time, input is provided via argv [1] and printf is wrapped in a function. When the input is larger than the buffer size, adjacent memory is overwritten. 0 watching Forks. We will learn how to daemonize a process and see how a server handles connectionsnet0: https://exploit.education/protostar/net-zero/-=[ Stuff I use ]=- M. Now if we use %n instead of %p at the 12th offset which has the address of changeme, it tries to perform arbitrary write on changeme and passes the condition of the program. Now we're getting into the three final exercises of Phoenix. You are piping the input in from the `stack-five-payload` file. These challenges are available for both 32 bit, and 64 bit mode.
