    Package : moodle
    Vulnerability : several
    Problem type : remote
    Debian-specific: no
    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

    DSA-2115-1 introduced a regression because it lacked a dependency on
    the wwwconfig-common package, leading to installations problems. This
    update addresses this issue. For reference, the text of the original
    advisory is provided below.

    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 1.8.13-2.

    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.

    Upgrade instructions
    - --------------------
