Link to Lab 7 Here

Lab 7 is exactly the same as Lab 6 except that the Front-end Back-end server pair is TE-CL, this means that the Back-end server does not support chunked encoding. The smuggled request:



Observe that the 'Content-Length' is less than the actual content-length to trick the server into leaving the rest of the request body which will serve as the next request.


The smuggled request has been executed, the server responds with the Administrator's Dashboard. All that is left is to delete Carlos:


The smuggled request has been executed:


Lab 7 Solved.

I have always wanted to write, partly to improve my writing skills but also to document my research in reverse code engineering, software exploitation and computer programming in general, my current goal is to have at least a post a week, but since am just starting out I do not know how feasible that will be considering school and my need for quality over quantity. In the coming weeks, I will post on varying topics from software reverse engineering to exploitation and basically anything that interest me. My primary aim is just to cement my knowledge in my fields of interest by giving back to the community as I learn and hopefully along the way help someone trying to learn. A quick disclaimer though is that I am no professional at either writing or the subject on which I will be writing (at least for now),  am just trying to navigate through the vast ocean of knowledge hoping to pick one or two things along the way, so corrections, constructive criticism, and even unconstructive o...

Bismillahirrahmanirrahim (In the name of Allah the most gracious, the most merciful) So recently I and @electro decided to solve wargames and CTFs in the spirit of honing the skills and because we are preparing for something really important (another post for another day). We decided to start with the labs at overthewire  and the first on the list was Bandit Lab. Bandit Lab was a fun experience, mostly easy, except for one or two tricky levels, level 26 and level 33 in particular. This Labs weren't so difficult but required a bit of thinking outside the box, hence why am documenting them. NB : this writeup doesn't include our thought process while solving the levels Level 26 Level Description When we attempt to login to this level using the private key obtained from the previous level we get automatically logged out and since the level goal already informed us that we are dealing with a different shell, we need to figure out what it is and how to break out of it. Above is the ...

  Lab 3: SSRF with blacklist-based input filter Task :  This lab has a stock check feature which fetches data from an internal system.  To solve the lab, change the stock check URL to access the admin interface at http://localhost/admin and delete the user carlos.  The developer has deployed two weak anti-SSRF defenses that you will need to bypass. This Lab is just like the previous ones except that we need to bypass blacklist filters. This is what a normal request to the stock check feature looks like: Passing http://localhost/admin to the stockApi parameter does not work this time. we get this response: That's the filter blocking us. It turned out 127.0.0.1, localhost, admin are all blacklisted so cannot be used. So after trying a couple things the following was able to bypass the filter: We get the following response: So to complete the Lab we just proceed to delete carlos. And that's it Lab solved.
