CVE-2021–3156 Sudo Vulnerability Exploit(By bl4sty)
The related links of this vulnerability information have been published.
But 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 16.04(It didn’t work)
Centos6(It didn’t work)
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.
