CVE Id(s) : CVE-2010-1613 CVE-2010-1614 CVE-2010-1615 CVE-2010-1616 CVE-2010-1617 CVE-2010-1618 CVE-2010-1619 CVE-2010-2228 CVE-2010-2229 CVE-2010-2230 CVE-2010-2231
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
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.
