# Linux/MIPS (Big Endian) - execve(/bin/sh) + Reverse TCP 192.168.2.157/31337 Shellcode (181 bytes)

# Author: cq674350529

# Date: 2018-10-07
|
|
# - execve('/bin/sh'), tcp - 192.168.2.157/31337
|
|
# - used in HTTP Request
|
|
# - tested on D-Link dir-850l router, avoid bad chars ('\x00', '\x20', '\x23', '\x0d\x0a')
|
|
# - based on rigan's shellcode and metasploit's shellcode, no encoder used
