The typo3 security team reports:

A crafted request to a vulnerable TYPO3 installation will allow an attacker to load PHP code from an external source and to execute it on the TYPO3 installation.

This is caused by a PHP file, which is part of the workspaces system extension, that does not validate passed arguments.

< 4.5.9

TYPO3 reports:

Extbase request handling fails to implement a proper access check for requested controller/ action combinations, which makes it possible for an attacker to execute arbitrary Extbase actions by crafting a special request. To successfully exploit this vulnerability, an attacker must have access to at least one Extbase plugin or module action in a TYPO3 installation. The missing access check inevitably leads to information disclosure or remote code execution, depending on the action that an attacker is able to execute.

Typo Security Team reports:

It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting, Information Disclosure, Insecure Unserialize leading to Arbitrary Code Execution.

TYPO3 Backend Help System - Due to a missing signature (HMAC) for a parameter in the view_help.php file, an attacker could unserialize arbitrary objects within TYPO3. We are aware of a working exploit, which can lead to arbitrary code execution. A valid backend user login or multiple successful cross site request forgery attacks are required to exploit this vulnerability.

TYPO3 Backend - Failing to properly HTML-encode user input in several places, the TYPO3 backend is susceptible to Cross-Site Scripting. A valid backend user is required to exploit these vulnerabilities.

TYPO3 Backend - Accessing the configuration module discloses the Encryption Key. A valid backend user with access to the configuration module is required to exploit this vulnerability.

TYPO3 HTML Sanitizing API - By not removing several HTML5 JavaScript events, the API method t3lib_div::RemoveXSS() fails to filter specially crafted HTML injections, thus is susceptible to Cross-Site Scripting. Failing to properly encode for JavaScript the API method t3lib_div::quoteJSvalue(), it is susceptible to Cross-Site Scripting.

TYPO3 Install Tool - Failing to properly sanitize user input, the Install Tool is susceptible to Cross-Site Scripting.

Olivier Dobberkau, Andreas Otto, and Thorsten Kahler report:

An unspecified error in the internal form engine can be used for sending arbitrary mail headers, using it for purposes which it is not meant for, e.g. sending spam messages.

Secunia reports:

Some vulnerabilities have been reported in Typo3, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting and session fixation attacks, and compromise a vulnerable system.

The "Install tool" system extension uses insufficiently random entropy sources to generate an encryption key, resulting in weak security.

The authentication library does not properly invalidate supplied session tokens, which can be exploited to hijack a user's session.

Certain unspecified input passed to the "Indexed Search Engine" system extension is not properly sanitised before being used to invoke commands. This can be exploited to inject and execute arbitrary shell commands.

Input passed via the name and content of files to the "Indexed Search Engine" system extension 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.

Certain unspecified input passed to the Workspace module 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.

Note: It is also reported that certain unspecified input passed to test scripts of the "ADOdb" system extension 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 website.

TYPO3 develop team reports:

Affected versions: TYPO3 versions 4.0.13 and below, 4.1.12 and below, 4.2.9 and below, 4.3.0beta1 and below.

SQL injection, Cross-site scripting (XSS), Information disclosure, Frame hijacking, Remote shell command execution and Insecure Install Tool authentication/session handling.

< 4.2.10

Typo Security Team reports:

Failing to properly encode the output, the default TYPO3 Exception Handler is susceptible to Cross-Site Scripting. We are not aware of a possibility to exploit this vulnerability without third party extensions being installed that put user input in exception messages. However, it has come to our attention that extensions using the extbase MVC framework can be used to exploit this vulnerability if these extensions accept objects in controller actions.

Typo Security Team reports:

TYPO3 Backend History Module - Due to missing encoding of user input, the history module is susceptible to SQL Injection and Cross-Site Scripting. A valid backend login is required to exploit this vulnerability. Credits go to Thomas Worm who discovered and reported the issue.

TYPO3 Backend API - Failing to properly HTML-encode user input the tree render API (TCA-Tree) is susceptible to Cross-Site Scripting. TYPO3 Versions below 6.0 does not make us of this API, thus is not exploitable, if no third party extension is installed which uses this API. A valid backend login is required to exploit this vulnerability. Credits go to Richard Brain who discovered and reported the issue.

Typo Security Team reports:

Extbase Framework - Failing to sanitize user input, the Extbase database abstraction layer is susceptible to SQL Injection. TYPO3 sites which have no Extbase extensions installed are not affected. Extbase extensions are affected if they use the Query Object Model and relation values are user generated input. Credits go to Helmut Hummel and Markus Opahle who discovered and reported the issue.

Access tracking mechanism - Failing to validate user provided input, the access tracking mechanism allows redirects to arbitrary URLs. To fix this vulnerability, we had to break existing behaviour of TYPO3 sites that use the access tracking mechanism (jumpurl feature) to transform links to external sites. The link generation has been changed to include a hash that is checked before redirecting to an external URL. This means that old links that have been distributed (e.g. by a newsletter) will not work any more.

Typo3 Security Report (TYPO3-CORE-SA-2012-003):

TYPO3 bundles and uses an external JavaScript and Flash Upload Library called swfupload. TYPO3 can be configured to use this Flash uploader. Input passed via the "movieName" parameter to swfupload.swf is not properly sanitised before being used in a call to "ExternalInterface.call()". This can be exploited to execute arbitrary script code in a user's browser session in context of an affected site. The existance of the swfupload library is sufficient to be vulnerable to the reported problem.

Secunia reports:

Some vulnerabilities have been reported in Typo3, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose sensitive information.

Input passed via unspecified fields to the backend user interface 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.

An error in the "jumpUrl" mechanism can be exploited to read arbitrary files from local resources by disclosing a hash secret used to restrict file access.

Typo Security Team reports:

It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting and Remote Code Execution.

TYPO3 bundles flash files for video and audio playback. Old versions of FlowPlayer and flashmedia are susceptible to Cross-Site Scripting. No authentication is required to exploit this vulnerability.

The file upload component and the File Abstraction Layer are failing to check for denied file extensions, which allows authenticated editors (even with limited permissions) to upload php files with arbitrary code, which can then be executed in web server's context.
