maas vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.10
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS


The cluster could be made to run programs as an administrator.

Software Description

  • maas - Ubuntu MAAS Server


James Troup discovered that MAAS stored RabbitMQ authentication credentials in a world-readable file. A local authenticated user could read this password and potentially gain privileges of other user accounts. This update restricts the file permissions to prevent unintended access. (CVE-2013-1069)

Chris Glass discovered that the MAAS API was vulnerable to cross-site scripting vulnerabilities. With cross-site scripting vulnerabilities, if a user were tricked into viewing a specially crafted page, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain. (CVE-2013-1070)
