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.
