[Security-news] SA-CONTRIB-2012-080 - Hostmaster (Aegir) - Access Bypass and Cross Site Scripting (XSS)

[security-news at drupal.org]

View online: http://drupal.org/node/1585678

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-080
  * Project: Hostmaster (Aegir) [1] (third-party module)
  * Version: 6.x
  * Date: 2012-May-16
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: Multiple vulnerabilities

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

.... Cross Site Scripting

CVE: Requested.
Hostmaster displays a log from tasks executed in Aegir's backend component,
provision. In certain circumstances these log messages were not escaped
properly before being displayed to the user. This vulnerability is mitigated
by the fact that people wishing to exploit this must have access to the PHP
code of either provision itself or one of the sites hosted by Aegir.

.... Access Bypass

CVE: Requested.
Hostmaster doesn't allow people to edit or create certain node types that are
used for the internal representation of data. The implementation of this
wasn't fully complete and would still allow privileged users to edit these
nodes. This can cause some data corruption in the front-end, leading to tasks
that would appear to never finish running. This vulnerability is mitigated by
the fact that people wishing to exploit this must have the 'edit package' or
'administer nodes' permissions, which are not given to any roles by the
default Aegir install.

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

  * Hostmaster 6.x-1.x versions prior to 6.x-1.9.

release which can be found at: http://community.aegirproject.org/1.9 [4]
