Lab Scoreboard

Lab Walkthrough Video:


In this lab exercise, the access logs of an Apache webserver are provided. Analyze the logs using LogFile Navigator (LNAV) and answer the following questions:

  1. SQLmap was used to perform an SQL injection attack against a particular webpage. Find the relative path of the vulnerable webpage.
  2. The most active user of the web application was suspected to be attacking it. Verify if that was actually the case. Also, find out the IP address of that user.
  3. Which attacker machine was able to find out the existence of directory '/btslab/tmp/'?
  4. How many union-based SQL injection attacks were attempted on the web application?
  5. How many of the requests resulted in an internal server error?
  6. An HTTP GET request was made to a web page to download a PDF file. The same web page was vulnerable to PATH traversal attack and was exploited to download /etc/passwd file. Find the approximate size of /etc/passwd file in KB.
  7. Which attacker machine had tried to perform the most command injection attempts using the 'exec' payload?
  8. How many onerror based XSS attacks were attempted on the web application?


Guidelines:

  • LNAV can be invoked by using `lnav` command.
  • Log file `access.json` is kept in the home directory of the root user.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
