By Drupal Security Team on
- Advisory ID: DRUPAL-SA-CONTRIB-2012-080
- Project: Hostmaster (Aegir) (third-party module)
- Version: 6.x
- Date: 2012-May-16
- Security risk: Less critical
- Exploitable from: Remote
- Vulnerability: Multiple vulnerabilities
Description
Cross Site Scripting
CVE: CVE-2012-2708.
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: CVE-2012-2707.
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.
