Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2015-3274)

The vulnerability is caused by an input validation error in the user_get_user_details function in user/lib.php in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3273)

The vulnerability allows a remote authenticated user to manipulate data.

mod/forum/post.php in Moodle 2.9.x before 2.9.1 does not consider the mod/forum:canposttomygroups capability before authorizing "Post a copy to all groups" actions, which allows remote authenticated users to bypass intended access restrictions by leveraging per-group authorization.


3) Input validation error (CVE-ID: CVE-2015-3272)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Open redirect vulnerability in the clean_param function in lib/moodlelib.php in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via vectors involving an HTTP Referer header that has a substring match with a local URL. <a href="http://cwe.mitre.org/data/definitions/601.html">CWE-601: URL Redirection to Untrusted Site ('Open Redirect')</a>
