Description


Dotclear <= 2.6.2 (categories.php) SQL Injection Vulnerability

[-] Software Link:

http://dotclear.org/

[-] Affected Versions:

Version 2.6.2 and probably prior versions.

[-] Vulnerability Description:

The vulnerable code is located in /admin/categories.php:

  1. Update order

  2. if (!empty($_POST['save_order']) && !empty($_POST['categories_order'])) {
  3. $categories = json_decode($_POST['categories_order']);
  4. foreach ($categories as $category) {
  5. if (!empty($category->item_id)) {
  6. $core->blog->updCategoryPosition($category->item_id, $category->left, $category->right);
  7. }
  8. }
  9. dcPage::addSuccessNotice(__('Categories have been successfully reordered.'));
  10. http::redirect('categories.php');
  11. }

User input passed through the $_POST['categories_order'] parameter is not properly sanitized before being used in a call to the dcBlog::updCategoryPosition() method at line 76. This could be exploited to conduct SQL injection attacks leveraging the UPDATE statement defined in the nestedTree::updatePosition() method. Successful exploitation of this vulnerability requires an account with the “manage categories” permission.

[-] Solution:

Update to version 2.6.3.
