Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Code Injection (CVE-ID: CVE-2013-3630)

The vulnerability allows a remote #AU# to read and manipulate data.

Moodle through 2.5.2 allows remote authenticated administrators to execute arbitrary programs by configuring the aspell pathname and then triggering a spell-check operation within the TinyMCE editor.


2) Input validation error (CVE-ID: CVE-2012-6087)

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

repository/s3/S3.php in the Amazon S3 library in Moodle through 2.2.11, 2.3.x before 2.3.9, 2.4.x before 2.4.6, and 2.5.x before 2.5.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, related to an incorrect CURLOPT_SSL_VERIFYHOST value.


3) SQL injection (CVE-ID: CVE-2013-4313)

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

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker 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.


4) Cross-site scripting (CVE-ID: CVE-2013-4341)

Vulnerability allows a remote attacker to perform Cross-site scripting attacks.

An input validation error exists in Moodle through 2.2.11, 2.3.x before 2.3.9, 2.4.x before 2.4.6, and 2.5.x before 2.5.2 when processing a crafted blog link within an RSS feed. 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.


5) Code Injection (CVE-ID: CVE-2013-5674)

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

badges/external.php in Moodle 2.5.x before 2.5.2 does not properly handle an object obtained by unserializing a description of an external badge, which allows remote attackers to conduct PHP object injection attacks via unspecified vectors, as demonstrated by overwriting the value of the userid parameter.
