Patches

Vulnerability mechanics

Root cause

"Missing input sanitization on the categories_order POST parameter before it is used in an SQL UPDATE statement."

Attack vector

An attacker must be authenticated with the "manage categories" permission [ref_id=1][ref_id=2]. The attacker sends a crafted POST request with `save_order` and `categories_order` parameters. The `categories_order` value is a JSON array whose `item_id`, `left`, and `right` properties are injected into an SQL UPDATE statement without sanitization [ref_id=1][ref_id=2]. By embedding SQL metacharacters in these JSON fields, the attacker can execute arbitrary SQL commands against the database [CWE-89].

Affected code

The vulnerable code is in `/admin/categories.php` at lines 70-82 [ref_id=1][ref_id=2]. User input from `$_POST['categories_order']` is passed unsanitized to `$core->blog->updCategoryPosition()` (line 76), which ultimately reaches the `nestedTree::updatePosition()` method where an UPDATE statement is constructed without proper escaping [ref_id=1][ref_id=2].

What the fix does

The advisory states that version 2.6.3 fixes the vulnerability, but no patch diff is included in the bundle [ref_id=1][ref_id=2]. The fix presumably adds proper input sanitization or parameterized queries to the `updCategoryPosition()` or `nestedTree::updatePosition()` methods so that user-supplied values from the JSON-decoded `categories_order` parameter are safely escaped before being used in the SQL UPDATE statement.

Preconditions

  • authAttacker must have a valid account with the 'manage categories' permission
  • networkAttacker must be able to send HTTP POST requests to /admin/categories.php
  • inputThe categories_order POST parameter must contain a crafted JSON payload with SQL injection in item_id, left, or right fields
