CVE-2015-3273

Name of the Vulnerable Software and Affected Versions Moodle versions 2.9.x through 2.9.0

Description The issue is related to insufficient access control in the mod/forum/post.php function of the Moodle learning management system. This can be exploited by a remote attacker to bypass existing access restrictions by leveraging group authorization. The problem arises because the mod/forum:canposttomygroups capability is not properly considered before authorizing certain actions, such as "Post a copy to all groups".

Recommendations For Moodle versions 2.9.x through 2.9.0, update to version 2.9.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the mod/forum/post.php function to minimize the risk of exploitation. Additionally, review and adjust group authorization settings to ensure that access restrictions are properly enforced.
