linux web server
This vulnerability can be exploited remotely only if:
* System is set to boot (load EFI binaries) over HTTP
* An attacker has man in the middle position already relative to boot server and target machine.
Vulnerability is actually in the possibility to spoof the boot server when the vulnerable machine is set to boot over HTTP. This attack scenario is viable for every network boot or provisioning protocol where man in the middle attack is possible (e.g. protocol has no authentication like PXE, with man it the middle position can sniff the credentials, etc).
Every machine that has PXE enabled is vulnerable to man in the middle attack where malicious boot binaries can be offered to the system to boot from, using a rouge server in the local network.
Other ways to exploit this vulnerability is for the attacker to have full, superuser privileges on the system already. Having complete control over the system (being already logged in as root) is game over anyway and represents a meaningless attack vector for this or any other vulnerability.
Thank you very much, Boss ❤, for this excellent educational tutorial. Boss, all new website pentesters, exploitor, and bug hunters would be very grateful to you if you help us regarding these big problems.
1. How to find the REAL ORIGIN IP behind WAF like Cloudflare, Akamai, ModSecurity, AWS CDN, etc.? If you find the origin IP, 50% of website bug hunting is completed.
2. How do we find vulnerable parameters and endpoints inside secure websites behind CMS?
3. How to find vulnerable parameters and endpoints inside .js, .json, .xml?
4. How to Double Encode Payloads to bypass WAF and CMS restrictions?
5. Suppose if the website is extremely secure and we can't find any vulnerabilities in it, then how to perform host header injection and HTTP request smuggling attacks for SQLI, XSS, LFI, RFI, RCE, OS COMMAND INJECTION 💉, etc.
Believe me, these topics will help you as well as all new website pentesters, exploitors, and website bug hunters to become successful in real-life website hacking, penetration, exploitation, bug hunting field.
Thank you and best regards,
🎉❤👌🏆✍️✌️🔥💐✔️❤️🔑💉✅️
