Wordpress "cat_id" Sql Injection Vulnerability


Recommended Posts

Secunia writes...


A vulnerability has been reported in WordPress, which can be exploited by malicious people to conduct SQL injection attacks.


Input passed to the "cat_ID" parameter isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.


The vulnerability has been reported in version 1.5. Other versions may also be affected.



Update to version

Well, now I guess I better find time to upgrade.  Thanks Thomas.  :P


They have instructions at the site for adding one line to one file, as an alternate to downloading and upgrading the whole package:


  1.  Open the wp-includes/template-functions-category.php file in a text editor like Wordpad.

  2. Go to around line 103 where it says get_the_category_by_ID.

  3. Create a new line after that and paste in $cat_ID = (int) $cat_ID;
