DESCRIPTION:
Some vulnerabilities have been reported in TYPO3, which can be
exploited by malicious users to conduct script insertion attacks,
disclose sensitive information, and perform certain actions with
escalated privileges and by malicious people to conduct cross-site
scripting attacks and disclose sensitive information.

1) Certain input passed to the "jumpUrl" mechanism in
typo3/sysext/cms/tslib/class.tslib_fe.php is not properly verified
before being used to read files and can be exploited to read
arbitrary files from local resources.

2) Certain input passed to the backend admin panel is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

3) Certain input is not properly verified in
typo3/sysext/em/mod1/class.em_index.php before being used to read
files. This can be exploited to read arbitrary files from local
resources via directory traversal sequences.

Successful exploitation requires admin permissions.

4) The application does not properly verify input passed to the
"sys_action" task "be_user_creation" before creating a user. This can
be exploited to create users who are members of arbitrary usergroups
and gain escalated privileges.

Successful exploitation requires requires permissions to create users
in the "taskcenter".

This vulnerability is reported in versions prior to 4.2.15 and
4.3.7.

5) Certain input is not properly sanitised in
typo3/contrib/RemoveXSS/RemoveXSS.php before being displayed to the
user. This can be exploited to insert arbitrary HTML and script code,
which will be executed in a user's browser session in context of an
affected site when the malicious data is being viewed.

The vulnerabilities are reported in versions prior to 4.2.15, 4.3.7,
and 4.4.4.

NOTE: A potential DoS due to a crash related to the "filter_var()"
PHP function has also been reported.

SOLUTION:
Update to version 4.2.15, 4.3.7, or 4.4.4.
