enrol/index.php in Moodle 2.6.x before 2.6.3 does not check for the moodle/course:viewhiddencourses capability before listing hidden courses, which allows remote attackers to obtain sensitive name and summary information about these courses by leveraging the guest role and visiting a crafted URL.

The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 2.4.x prior to 2.4.10, 2.5.x prior to 2.5.6, 2.6.x prior to 2.6.3, and all previous releases are exposed to the following vulnerabilities :

  - A cross-site request forgery (CSRF) vulnerability affects the quick-grading function. Session checking was not being performed correctly in Assignment's quick-grading, allowing forged requests to be made unknowingly by authenticated users. (MSA-14-0014 / CVE-2014-0213)

  - A security bypass weakness affects session Token expiration in MoodleMobile. Tokens created automatically in 'login/token.php' are valid forever. (MSA-14-0015 / CVE-2014-0214)

  - An information disclosure flaw which exposes student details through the use of a screen reader or viewing the HTML source code. (MSA-14-0016 / CVE-2014-0215)

  - An authorization bypass vulnerability exists because it fails to restrict access to the files linked in HTML blocks on 'My Home' page. Successful exploits will allow attackers to gain unauthorized access to these files. (MSA-14-0017 / CVE-2014-0216)

  - An information disclosure flaw that may allow a remote attacker to gain access to the details of hidden courses on enrollment pages via URL manipulation. (MSA-14-0018 / CVE-2014-0217)

  - A reflected cross-site scripting (XSS) vulnerability affects the URL downloader repository due to a lack of filtering. (MSA-14-0019 / CVE-2014-0218)

Moodle upstream has released versions 2.7, 2.6.3, 2.5.6, and 2.4.10 to fix the following security flaws :

CVE-2014-0213 MSA-14-0014: Cross-site request forgery possible in Assignment CVE-2014-0214 MSA-14-0015: Web service token expiry issue for MoodleMobile CVE-2014-0215 MSA-14-0016: Anonymous student identity revealed in assignment CVE-2014-0216 MSA-14-0017: File access issue in HTML block CVE-2014-0217 MSA-14-0018: Information leak in courses CVE-2014-0218 MSA-14-0019: Reflected XSS in URL downloader repository
