Course Description

Who should take this course?

This course is for seasoned red teamers, penetration testers, security and vulnerability assessment analysts, and system administrators who want to know how to exploit and protect against the latest vulnerabilities impacting enterprise systems.

What are the prerequisites for this course?

Before taking this course, we recommend that you have basic knowledge of Python as a programming language, as well as functional knowledge of web applications.

Why take this course?

What makes this vulnerability so dangerous is anyone who is able to contact the server can perform RCE using OGNL. What is even more concerning is incident response companies, such as Volexity, have seen active exploitation of this vulnerability in the wild. Attackers can write to victim servers and allow them to perform malicious actions. With the wide use of Confluence, it is imperative that defenders act quickly to patch their servers and determine if any malicious actors exploited this vulnerability.

What makes this course different from others?

By the end of this course, you should be able to:

  • Define the vulnerability, describe its root cause, and communicate its significance to key organizational stakeholders.
  • Exploit this vulnerability using publicly available exploit code.
  • Execute various mitigation tactics to reduce risk.
