A blog site on our Real life experiences with various phases of DevOps starting from VCS, Build & Release, CI/CD, Cloud, Monitoring, Containerization.
Recently, I’ve been working on a project where we have a very large team. After the new feature is developed, the developers need to test the feature’s function. So we need to install some test tools on the server for testing purposes and we have to do this activity very frequently. Also, I wanted to schedule planned activities without an integrated third party tool with Ansible.
So, this is my writeup on how I was able to achieve my first Remote Code Execution. Also after reviewing the code I was able to understand more about malicious code execution via OS functions. Finally, I was able to capture the flag and get the Hall of Fame.
Out of Band(OOB) Command Injection is performed by sending a DNS request to a server, which occurs when input data is interpreted as an operating system command. By this, an attacker can execute arbitrary commands on the system and gain unauthorized access.
Today in the Era of DevOps and automation, we expect everything to be as quick as the click of a button and whenever the term ‘DevOps’ comes to our mind a bunch of CI-CD tools pop up automatically, Azure DevOps is on such tool of capabilities.
None of us wants to use the conventional ways to of adding manual steps to our DevOps implementation these days, which is where Azure DevOps provides us with the option of Azure pipelines which we opted for our project implementation but still we don’t want to write the same pipeline code for every application, that’s where the Azure pipeline template steps in, we will discuss how I setup and implement Azure pipeline template in my projects.

When I set forth with my journey of containerization with docker, I have gone through a misconception that Overlay networking in docker can’t be set up without any orchestrator like Docker swarm, Kubernetes. But after spending some time with containers I realized that I was wrong, Orchestrators leverage the functionality of overlay networking but it is not true that we cannot use overlay networks without any swarm or Kubernetes.
As we all know that the caching is a process that everyone uses using different topologies like caching at application node, geographical caching, even some organizations set up a completely dedicated cluster of nodes only for caching.
In this blog, we will discuss setting up Geographical caching using Cloudflare’s Content delivery network and Cloudflare’s workers.
