[-] Software Link:
[-] Affected Versions:
Version 2.6.2 and probably prior versions.
[-] Vulnerability Description:
The vulnerable code is located in /admin/categories.php:
$categories = json_decode($_POST['categories_order']);
foreach ($categories as $category) {
if (!empty($category->item_id)) {
$core->blog->updCategoryPosition($category->item_id, $category->left, $category->right);
}
}
dcPage::addSuccessNotice(__('Categories have been successfully reordered.'));
http::redirect('categories.php');
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 βmanage categoriesβ permission.
[-] Solution:
Update to version 2.6.3.
