Tools I have created

In penetration testing Web and android I've created some tools to help researchers in Recon and penetration testing proccess like: aboutsub

https://github.com/M359AH/aboutsub

aboutsub Is help researchers to find the ports opened on the subdomains so attacker/researcher may can use it for exploit some service or misconfiguration on some serivce on this port

https://github.com/M359AH/DepFine

DepFine it based on dependency confusion vulnerability so you give this tool the raw link of the package.json file and the tool will search for the dependencies and get the Vulnrable dependency allow attacker to claim it and takeover the dependency and this lead to RCE Vulnerability and I've founded on a lot of sites

Writeups about my Vulnerabilites

I've found some vulnerability with a wonderful thinks so I have blog on medium to share my logic vulnerabilites with a new things like :

https://medium.com/@Hossam.Mesbah/ghost-let-me-inject-os-commands-rce-a6e71e54445d

This blog about Vulnerability I have found in some site RCE From file upload page but It's blind and I make it allow to access commands and see /etc/passwd from a blind RCE To full RCE Vulnerability

Also this is priveleges escalation I've found on private program on H1 Platform

https://medium.com/@Hossam.Mesbah/owner-is-lier-privileges-escalation-36ade728f2fb?source=your_stories_page

It gave the normal user the admin perrmissions and can delete the admin

Then the IDOR Vulnerability Blog maybe the manager is hacker is gave the normal user access to delete the admin from the project permanently

https://medium.com/@Hossam.Mesbah/maybe-the-manager-is-hacker-idor-d005f49aa0a3?source=your_stories_page

Also this CSRF Vulnerability allow attacker to exploit on the same Affected site without host his script on external website
