Vulnerability scans and penetration test are often used interchangeably. Unfortunately, it is the improper use that creates confusions, sometimes around security decisions too. This article shal help the reader with these terms: penetration testing vs vulnerability scanning, their project inputs, outputs, security health indicators and decision making factors.
Imagine you are a Java programmer and that you just decided you want to use Snyk Open Source scanning to help you find security problems in your third party libraries. Good call! However, after connecting your repository to the Snyk Open Source scanner, you find out that you have ten or maybe even 50 vulnerabilities in the packages you depend on. The major question is: where do I start?
A recent privilege escalation heap overflow vulnerability (CVSS 7.8), CVE-2021-3156, has been found in sudo. sudo is a powerful utility built in almost all Unix-like based OSes. This includes Linux distributions, like Ubuntu 20 (Sudo 1.8.31), Debian 10 (Sudo 1.8.27), and Fedora 33 (Sudo 1.9.2). This popular tool allows users to run commands with other user privileges.
On January 26th, 2021, Qualys reported that many versions of SUDO (1.8.2 to 1.8.31p2 and 1.9.0 to 1.9.5p1) are vulnerable (CVE-2021-3156) to a buffer overflow attack dubbed Baron Samedit that can result in privilege escalations. Qualys was able to use this vulnerability to gain root on at least Ubuntu 20.04 (Sudo 1.8.31), Debian 10 (Sudo 1.8.27), and Fedora 33 (Sudo 1.9.2), some of the most modern and widely used Linux operating systems.

User authentication – the process of ensuring only authorized users have access to controlled data and functionality – is the fundamental cornerstone of web and application security.
The Common Vulnerability Scoring System (CVSS) can help you navigate the constantly growing ocean of open source vulnerabilities. But it’s difficult to lend your trust and put the security of your organization and your customers into the hands of a system that you may know very little about. Let’s take a closer look at the CVSS to see what it’s all about.
Remote Desktop Protocol (RDP) is a communication protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection[1]. Once connected, the remote user will be able to communicate with the machine using their input devices, keyboard and mouse, and to have their screen displaying the output of their actions – as if they were physically connected. Simply put, gaining access to your crown jewels.
