More information:

Several remote vulnerabilities have been discovered in Moodle, a course management system. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2010-1613
Moodle does not enable the Regenerate session id during login setting by default, which makes it easier for remote attackers to conduct session fixation attacks.
CVE-2010-1614
Multiple cross-site scripting (XSS) vulnerabilities allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) the Login-As feature or (2) when the global search feature is enabled, unspecified global search forms in the Global Search Engine.
CVE-2010-1615
Multiple SQL injection vulnerabilities allow remote attackers to execute arbitrary SQL commands via vectors related to (1) the add_to_log function in mod/wiki/view.php in the wiki module, or (2) data validation in some forms elements related to lib/form/selectgroups.php.
CVE-2010-1616
Moodle can create new roles when restoring a course, which allows teachers to create new accounts even if they do not have the moodle/user:create capability.
CVE-2010-1617
user/view.php does not properly check a role, which allows remote authenticated users to obtain the full names of other users via the course profile page.
CVE-2010-1618
A Cross-site scripting (XSS) vulnerability in the phpCAS client library allows remote attackers to inject arbitrary web script or HTML via a crafted URL, which is not properly handled in an error message.
CVE-2010-1619
A Cross-site scripting (XSS) vulnerability in the fix_non_standard_entities function in the KSES HTML text cleaning library (weblib.php) allows remote attackers to inject arbitrary web script or HTML via crafted HTML entities.
CVE-2010-2228
A Cross-site scripting (XSS) vulnerability in the MNET access-control interface allows remote attackers to inject arbitrary web script or HTML via vectors involving extended characters in a username.
CVE-2010-2229
Multiple cross-site scripting (XSS) vulnerabilities in blog/index.php allow remote attackers to inject arbitrary web script or HTML via unspecified parameters.
CVE-2010-2230
The KSES text cleaning filter in lib/weblib.php does not properly handle vbscript URIs, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via HTML input.
CVE-2010-2231
A Cross-site request forgery (CSRF) vulnerability in report/overview/report.php in the quiz module allows remote attackers to hijack the authentication of arbitrary users for requests that delete quiz attempts via the attemptid parameter.

This security update switches to a new upstream version and requires database updates. After installing the fixed package, you must visit <http://localhost/moodle/admin/> and follow the update instructions.

For the stable distribution (lenny), these problems have been fixed in version 1.8.13-1.

For the unstable distribution (sid), these problems have been fixed in version 1.9.9.dfsg2-1.

We recommend that you upgrade your moodle package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
