Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2012-3398)

The vulnerability allows a remote #AU# to perform service disruption.

Algorithmic complexity vulnerability in Moodle 1.9.x before 1.9.19, 2.0.x before 2.0.10, 2.1.x before 2.1.7, and 2.2.x before 2.2.4 allows remote authenticated users to cause a denial of service (CPU consumption) by using the advanced-search feature on a database activity that has many records. Per: http://cwe.mitre.org/data/definitions/407.html 'CWE-407: Algorithmic Complexity'


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3390)

The vulnerability allows a remote #AU# to gain access to sensitive information.

lib/filelib.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4 does not properly restrict file access after a block has been hidden, which allows remote authenticated users to obtain sensitive information by reading a file that is embedded in a block.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3391)

The vulnerability allows a remote #AU# to gain access to sensitive information.

mod/forum/rsslib.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4 does not properly implement the requirement for posting before reading a Q&A forum, which allows remote authenticated users to bypass intended access restrictions by leveraging the student role and reading the RSS feed for a forum.


4) Configuration (CVE-ID: CVE-2012-3392)

The vulnerability allows a remote #AU# to manipulate or delete data.

mod/forum/unsubscribeall.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4 does not consider whether a forum is optional, which allows remote authenticated users to bypass forum-subscription requirements by leveraging the student role and unsubscribing from all forums.


5) Cross-site scripting (CVE-ID: CVE-2012-3393)

Vulnerability allows a remote attacker to perform XSS attacks.

The vulnerability is caused by an input validation error in repository/lib.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4. A remote authenticated 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.


6) SQL injection (CVE-ID: CVE-2012-3395)

The vulnerability allows a remote user to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote privileged user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
