https://twitter.com/bl4sty/status/1355473814117867528But I’m not going to study its internal principle,just want to exploit this vulnerability accroding to the article which is published on twitter.
Learning makes me happy :）
I will run the exploit code on different kinds of linux to reproduce this vulnerability.
Kali Liunx 2019.4
Ubuntu 18.04
ubuntu 16.04(It didn’t work)
Centos6(It didn’t work)
Other
But I found it did not work on centos6,and ubuntu version< 2018,and due to conditions that I do not have all kinds of linux system,so only partly system are tested.
