When users change their password existing sessions for that particular user account are not revoked. A valid backend or frontend user account is required in order to make use of this vulnerability.
The element information component used to display properties of a certain record is susceptible to information disclosure. The list of references from or to the record is not properly checked for the backend user’s permissions. A valid backend user account is needed in order to exploit this vulnerability.
It has been discovered that login failures have been logged on the default stream with log level "warning" including plain-text user credentials.
Failing to properly encode user input, backend forms are vulnerable to Cross-Site Scripting. A valid backend user account is needed to exploit this vulnerability.
Failing to properly encode user input, several places of the TYPO3 CMS are vulnerable to Cross-Site Scripting.
Failing to properly validate incoming data, the suggest wizard is susceptible to insecure unserialize. To exploit this vulnerability a valid backend user account is needed.
Links with a valid cHash argument lead to newly generated page cache entries. Because the cHash is not bound to a specific page, attackers could use valid cHash arguments for multiple pages, leading to additional useless page cache entries. Depending on the number of pages in the system and the number of available valid links with a cHash, attackers could add a considerable amount of additional cache entries, which in the end exceed storage limits and thus could lead to the system not responding any more. This means the Cache Flooding attack potentially could lead to a successful Denial of Service (DoS) attack.
Due to late TCA initialization the authentication service fails to restrict frontend user according to the validation rules. Therefore it is possible to authenticate restricted (e.g. disabled) frontend users.
It has been discovered that TYPO3’s Salted Password system extension (which is a mandatory system component) is vulnerable to Authentication Bypass when using hashing methods which are related by PHP class inheritance. In standard TYPO3 core distributions stored passwords using the blowfish hashing algorithm can be overridden when using MD5 as the default hashing algorithm by just knowing a valid username. Per default the Portable PHP hashing algorithm (PHPass) is used which is not vulnerable.
Failing to properly check user permission on file storages, editors could gain knowledge of protected storages and its folders as well as using them in a file collection being rendered in the frontend. A valid backend user account is needed to exploit this vulnerability.
Phar files (formerly known as "PHP archives") can act als self extracting archives which leads to the fact that source code is executed when Phar files are invoked. The Phar file format is not limited to be stored with a dedicated file extension - "bundle.phar" would be valid as well as "bundle.txt" would be. This way, Phar files can be obfuscated as image or text file which would not be denied from being uploaded and persisted to a TYPO3 installation. Due to a missing sanitization of user input, those Phar files can be invoked by manipulated URLs in TYPO3 backend forms. A valid backend user account is needed to exploit this vulnerability. In
HTTP requests being performed using the TYPO3 API expose the specific TYPO3 version to the called endpoint.
Failing to properly dissociate system related configuration from user generated configuration, the Form Framework (system extension "form") is vulnerable to SQL injection and Privilege Escalation. Basically instructions can be persisted to a form definition file that were not configured to be modified - this applies to definitions managed using the form editor module as well as direct file upload using the regular file list module. A valid backend user account as well as having system extension form activated are needed in order to exploit this vulnerability.
TYPO3 uses the package swiftmailer/swiftmailer for mail actions. This package is known to be vulnerable to Remote Code Execution.
Due to a missing file extension in the fileDenyPattern, backend user are allowed to upload *.pht files which can be executed in certain web server setups. The new default fileDenyPattern is the following, which might have been overridden in the TYPO3 Install Tool. ``` \.(php[3-7]?|phpsh|phtml|pht)(\..*)?$|^\.htaccess$ ```
It has been discovered that the Form Framework (system extension "form") is vulnerable to Insecure Deserialization when being used with the additional PHP PECL package “yaml”, which is capable of unserializing YAML contents to PHP objects. A valid backend user account as well as having PHP setting "yaml.decode_php" enabled is needed to exploit this vulnerability (which is the default value according to PHP documentation).
All link fields within the TYPO3 installation are vulnerable to Cross-Site Scripting as authorized editors can insert data commands by using the url scheme "data:".
Failing to properly encode user input, the page module is vulnerable to Cross-Site Scripting. A valid backend user account with permissions to edit plugins is needed to exploit this vulnerability.
Make sure to not expose the vendor directory to the publicly accessible document root. In composer managed installation, make sure to configure a dedicated web folder. In general it is recommended to not expose the complete typo3_src sources folder in the document root.
The TYPO3 backend module stores the username of an authenticated backend user in its cache files. By guessing the file path to the cache files it is possible to receive valid backend usernames.
