SecurityvulnsSECURITYVULNS:DOC:28012XSS, CSRF and AFU vulnerabilities in Organizer for WordPress
Hello 3APA3A!
I want to warn you about multiple security vulnerabilities in plugin Organizer for WordPress. This is the second in series of advisories concerning vulnerabilities in this plugin.
These are Cross-Site Scripting (reflected and persistent), Cross-Site Request Forgery and Arbitrary File Upload (Code Execution) vulnerabilities.
Affected products:
Vulnerable are Organizer 1.2.1 and previous versions.
As answered me the developer of the plugin, he doesn't support it anymore and will not be fixing any vulnerabilities in it.
Details:
XSS (WASC-08):
XSS (Persistent) (WASC-08):
Exploit:
http://websecurity.com.ua/uploads/2012/Organizer%20XSS-2.html
Code will execute at the page users.php of the plugin.
CSRF (WASC-09):
Via attack on function Add/Edit User Setting (which combined into the same POST request) it's possible to add and edit settings.
POST request at page http://site/wp-admin/admin.php?page=organizer/page/users.php. Similarly to above exploit for XSS.
Via attack on function Delete User Setting it's possible to delete settings.
http://site/wp-admin/admin.php?page=organizer/page/users.php&delete_id=admin
Arbitrary File Upload (Code Execution) (WASC-31):
It's possible to upload arbitrary files with code execution (php files). Because in field "File extensions allowed" it's possible to set extensions of scripts, such as "php".
This will allow to upload to the server and execute arbitrary scripts. Besides attacking admin via above-mentioned CSRF vulnerability for changing of the settings (or getting access to admin account for this), the Insufficient Authorization vulnerability (described in the third advisory) also can be used for this (in the presence of account even with lowest rights as Subscriber).
Timeline:
