In this blog post, we discuss two vulnerabilities that were identified during my research on HTTP Request Smuggling:
- Node.js - CVE-2023-30589
- Gunicorn - CVE-2024-1135
This year I contributed 2 challenges to bi0s CTF (formerly InCTF Internationals).
In this post, we discuss the intended solution to PyCGI challenge. The source code of this challenge can be downloaded from here.
#
Analysis
We are provided with 2 attachments for this challenge:
- Dockerfile
- Nginx.conf
Looking into the Nginx configuration, we can find that there is a potential path traversal in the /static endpoint. You can read more about this here.
In this post, we discuss the solution to EmoLocker challenge from bi0s CTF 2022. The source code of this challenge can be downloaded from here.
#
Analysis
Upon opening the challenge link, we are presented with a lockscreen that uses emojis instead of numbers. The page has two features: register and login. Additionally, there is an admin bot, which suggests that the challenge may involve client-side concepts.
As I look back at my three and a half years at Amrita University and Team bi0s, I can’t help but feel a sense of nostalgia. Join me as I take a trip down memory lane, and reflect on the experiences, lessons, and achievements that have shaped me into the person I am today.

🚌 Journey so far..
As I reflect on the past few years, I am struck by the impact that time has had on me. I have grown and changed in ways I never could have imagined. My experiences at Amrita and Team bi0s have helped me to broaden my perspective and gain a deeper understanding of the world around me. I am proud of the progress I have made, both academically and personally, and acknowledge that there were times when I felt lost and uncertain. But it was during those moments that I learned the value of taking a step back, re-evaluating my goals and redirecting my efforts.
