Vulnerable subcomponent #1: Frontend




Vulnerability Type: Cross-Site Scripting
Severity: High
Suggested CVSS v2.0: AV:N/AC:M/Au:N/C:N/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Failing to properly sanitize URL parameters the
"JSwindow" property of the typolink function is susceptible to
Cross-Site Scripting. The problem does not exist if the third party
extension "realurl" is used and it's configuration parameter
"doNotRawUrlEncodeParameterNames" is set to FALSE (default).




Vulnerable subcomponent #2: Backend



Vulnerability Type: Information Disclosure
Severity: Low
Suggested CVSS v2.0: AV:N/AC:M/Au:N/C:P/I:N/A:N/E:U/RL:OF/RC:C
Problem Description: For authentication attempts with wrong credentials,
TYPO3 sends different HTTP-Headers depending if provided username or
provided password is wrong.


Vulnerability Type: Authentication Delay Bypass
Severity: Low
Suggested CVSS v2.0: AV:N/AC:M/Au:N/C:P/I:N/A:N/E:U/RL:OF/RC:C
Problem Description: The TYPO3 Backend login has a delay for
authentication attempts with wrong credentials. By using a crafted
request, an attacker is able to bypass the madantory delay in such cases.


Vulnerability Type: Cross-Site Scripting
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:L/Au:S/C:N/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Failing to properly sanitize an username the admin
panel is susceptible to Cross-Site Scripting.


Vulnerability Type: Cross-Site Scripting
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:H/Au:S/C:P/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Failing to properly sanitize a content element's
link attribute the browse_links wizard is susceptible to Cross-Site
Scripting. Exploiting requires an attacker to prepare a content element
and trick its victim to open the browse_links wizard for this record.


Vulnerability Type: Cross-Site Scripting
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:H/Au:S/C:P/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Failing to properly sanitize a page title the
system extension recycler is susceptible to Cross-Site Scripting.
Exploiting requires an attacker to prepare a page and deleted page and
trick its victim to visit the recycler.


Vulnerability Type: Cross-Site Scripting
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:H/Au:S/C:P/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Failing to properly sanitize a page title the
tcemain flash message is susceptible to Cross-Site Scripting. Exploiting
requires an attacker to prepare a page and trick its victim to copy/move
the prepared page.


Vulnerability Type: Information Disclosure
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:L/Au:S/C:P/I:N/A:N/E:U/RL:OF/RC:C
Problem Description: A TYPO3 Backend user (editor) is able to see
workspace changes of records in any languages - even for those he hasn't
got granted access to.


Vulnerability Type: Information Disclosure
Severity: High
Suggested CVSS v2.0: AV:N/AC:L/Au:S/C:C/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: Using "getText" feature on headlines of content
elements it is possible to retrieve arbitrary data from TYPO3 database.
The vulnerability results from an insecure configuration in
css_styled_content system extension.

Important Note: Having an adjusted fontTag property in the provided
TypoScript (e.g. lib.stdheader.10.1.fontTag) or depending on headlines
passed through fontTag might result in unexpected rendering results.
Headline rendering is now handled through dataWrap (e.g.
lib.stdheader.10.1.dataWrap). Make sure to check your TypoScript before
the update and check the wesite rendering after it!


Vulnerability Type: Unserialize() vulnerability
Severity: High
Suggested CVSS v2.0: AV:N/AC:M/Au:S/C:P/I:C/A:N/E:U/RL:OF/RC:C
Problem Description: Special user input of BE editors is treated as
serialized data and is deserialized by TYPO3. This allows BE editors to
delete any arbitrary file the webserver has access to.





Vulnerable subcomponent #3: Exposed API



Vulnerability Type: Cross-Site Scripting
Severity: Medium
Suggested CVSS v2.0: AV:N/AC:M/Au:N/C:P/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: The RemoveXSS function fails to sanitize an attack
vector that works in Internet Explorer version 6.


Vulnerability Type: Missing Access Control
Severity: High
Suggested CVSS v2.0: AV:N/AC:M/Au:S/C:P/I:P/A:N/E:U/RL:OF/RC:C
Problem Description: ExtDirect endpoints are not associated with TYPO3
backend modules and such TYPO3 access control is not applied on
ExtDirect calls. This allows arbitrary BE users to consume any available
ExtDirect endpoint service.
