Associated Vulnerability

Title:Sudo 缓冲区错误漏洞 (CVE-2019-18634)
Description:In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. (pwfeedback is a default setting in Linux Mint and elementary OS; however, it is NOT the default for upstream and many other packages, and would exist only if enabled by an administrator.) The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c.

Description

exploit for sudo CVE-2019-18634

Readme

# CVE-2019-18634

I wrote this exploit for Linx Mint 19.1 so probably it'll not work for other distributions. If you're exploint a real environment I recommend you to use Salem Rashid's exploit version, which has the proper offsets for other sudo versions.

This is just an exploit for this specfic OS, so perhaps not a full reliable exploit for other distros.
