course/loginas.php in Moodle through 2.2.11, 2.3.x before 2.3.11, 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1 does not enforce the moodle/site:accessallgroups capability requirement for outside-group users in a SEPARATEGROUPS configuration, which allows remote authenticated users to perform "login as" actions via a direct request.

The remote web server hosts Moodle, an open-source course management system.  Versions of Moodle 2.3.x prior to 2.3.11 are exposed to the following vulnerabilities :

 - A flaw exists that is due to the program failing to apply group constraints when handling a request from a specially crafted URL.  This may allow a remote attacker to bypass authentication and login as a user outside of the groups in which they are authorized to do so. (CVE-2014-0009)
 - A flaw exists as HTTP requests to 'user/profile/index.php' do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions.  By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to delete custom user profile fields and categories. (CVE-2014-0010)

 - A flaw exists that is due to the program recording some users' passwords and exposing them in plaintext in the config log report.  This may allow an authenticated remote attacker to gain access to password information. (CVE-2014-0008)
