Router vulnerability reproduce the ultimate Upanishads--based on the MIPS shellcode writing-vulnerability warning-the black bar safety net

Foreword Today we talk about how in the MIPS architecture to write shellcode for. In the previous two articles, we were introduced based on the MIPS buffer overflow practice, and further how to use learn to the overflow of knowledge reproduction and verification of router vulnerabilities. But in...
