Secunia Security Advisory - Multiple vulnerabilities and security issues have been reported in TYPO3, which can be exploited by malicious users to conduct SQL injection attacks, manipulate certain data, and compromise a vulnerable system and by malicious people to conduct cross-site scripting attacks, HTTP redirect attacks, HTTP response splitting attacks, session fixation attacks, bypass certain security restrictions, and disclose potentially sensitive information.

DESCRIPTION:
Multiple vulnerabilities and security issues have been reported in
TYPO3, which can be exploited by malicious users to conduct SQL
injection attacks, manipulate certain data, and compromise a
vulnerable system and by malicious people to conduct cross-site
scripting attacks, HTTP redirect attacks, HTTP response splitting
attacks, session fixation attacks, bypass certain security
restrictions, and disclose potentially sensitive information.
1) Input passed to unspecified parameters in the backend 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.
2) Input passed to unspecified parameters in the backend is not
properly sanitised before being returned to the user. This can be
exploited to redirect a user to an arbitrary site.
3) Input passed via the backend record editing forms is not properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires "editor" permissions.
4) A security issue exists when validating uploaded files via the
"fileDenyPattern" configuration variable and can be exploited to
execute arbitrary PHP code by uploading a PHP file with e.g. a
".phtml" file extension.
Successful exploitation requires backend permissions.
5) A security issue exists when an extension with a defective backend
module is installed and can be exploited to disclose the full path of
the application via error messages.
6) Certain input is not properly sanitised before being returned to
the user in the Extension Manager. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.
7) Input passed to unspecified parameters in the Extension Manager is
not properly verified before being used to update files. This can be
exploited to modify arbitrary files.
Successful exploitation requires admin permissions.
8) Certain input is not properly sanitised before being used to
construct an email message and can be exploited to inject arbitrary
email addresses.
9) Input passed to the "jumpurl" parameter is not properly sanitised
before being returned to the user. This can be exploited to insert
arbitrary HTTP headers, which are included in a response sent to the
user.
10) Input passed to the frontend login box 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.
This vulnerability is reported in versions prior to 4.2.13, prior to
4.3.4 and in 4.4 only.
11) A security issue exists in the "Forgot password" mechanism due to
predictable generation of the confirmation code. This can be exploited
to reset the password of a valid user using a predicted confirmation
code.
This vulnerability is reported in versions prior to 4.3.4 and in 4.4
only.
12) An error in the handling of sessions of install tool users can be
exploited to hijack another user's session.
13) Input passed to the extbase extension in the FLUID Templating
Engine 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.
This vulnerability is reported in versions prior to 4.3.4 and in 4.4
only.
14) A security issue exists in the HTML mailing API class
"t3lib_htmlmail" and can be exploited to disclose the version of the
application via mail headers.
This vulnerability is reported in versions prior to 4.2.13, prior to
4.3.4 and in 4.4 only.
15) Input passed to the frontend search box 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.
This vulnerability is reported in version 4.4 only.
The vulnerabilities are reported in versions prior to 4.1.14, prior
to 4.2.13, prior to 4.3.4 and in 4.4.
SOLUTION:
Update to version 4.1.14, 4.2.13, 4.3.4, and 4.4.1.
