Drupal Cross-Site Request Forgery and Security Bypass

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/31460/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data, Exposure
of sensitive information

WHERE:
>From remote

SOFTWARE:
Drupal 6.x
http://secunia.com/product/17839/

DESCRIPTION:
Two vulnerabilities have been reported in Drupal, which can be
exploited by malicious users to bypass certain security restrictions,
and by malicious people to conduct cross-site request forgeries.

1) A vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to
submit cached forms and forms containing AHAH elements and upload
files, by enticing a logged-in user to visit a malicious web page.

2) A vulnerability is caused due to improper access restriction in
the Upload module. This can be exploited to edit nodes, delete files,
and download attachments without having valid access rights.

Successful exploitation of this vulnerability requires valid user
credentials with the "upload files" permission.

The vulnerabilities are reported in all 6.x versions prior to 6.4.

SOLUTION:
Update to version 6.4.
