Svim korisnicima ove nadogradnje preporučuje se instalacija nove verzije.

* Advisory ID: DRUPAL-SA-CONTRIB-2011-051
* Project: HotBlocks [1] (third-party module)
* Version: 6.x
* Date: 2011-November-02
* Security risk: Less critical [2]
* Exploitable from: Remote
* Vulnerability: Access bypass, Cross Site Scripting, Cross Site Request
Forgery

-------- DESCRIPTION
---------------------------------------------------------

The HotBlocks module provides a rich experience for managing blocks.
The module contained multiple vulnerabilities including Cross Site Scripting
(XSS), Access Bypass, and Cross Site Request Forgery (CSRF).
XSS is mitigated by the fact that an attacker must have a role with the
permission "administer hotblocks". The Access Bypass is mitigated by the fact
that the module's author intended (but did not document) the bypass as a
feature. The CSRF issue requires an authenticated user with sufficient
permissions to be tricked into visiting a specially crafted URL.

-------- VERSIONS AFFECTED
---------------------------------------------------

* HotBlocks 6.x-1.x versions prior to 6.x-1.6.

Drupal core is not affected. If you do not use the contributed HotBlocks [3]
module, there is nothing you need to do.

-------- SOLUTION
------------------------------------------------------------

Install the latest version:

* If you use the HotBlocks module for Drupal 6.x, upgrade to HotBlocks
6.x-1.6 [4]

See also the HotBlocks [5] project page.
