Cross-site Scripting
TYPO3 is vulnerable to cross-site scripting. Corresponding rendering instructions via TypoScript functionality HTMLparser does not consider all potentially malicious HTML tag & attribute combinations per default. In default scenarios, a valid backend user account is needed to exploit this vulnerability. In case custom plugins used in the website frontend accept and reflect rich-text content submitted by users, no authentication is required.

TYPO3 Install Tool vulnerable to Code Execution
### Problem
Several settings in the Install Tool for configuring the path to system binaries were vulnerable to code execution. Exploiting this vulnerability requires an administrator-level backend user account with system maintainer permissions.

The corresponding change for this advisory involves enforcing the known disadvantages described in [TYPO3-PSA-2020-002: Protecting Install Tool with Sudo Mode](https://typo3.org/security/advisory/typo3-psa-2020-002).

### Solution
Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described.

### Credits
Thanks to Rickmer Frier & Daniel Jonka who reported this issue and to TYPO3 core & security team member Benjamin Franzke who fixed the issue.

Exposure of Sensitive Information to an Unauthorized Actor
TYPO3 is an open source PHP based web content management system released under the GNU GPL. Password hashes were being reflected in the editing forms of the TYPO3 backend user interface. This allowed attackers to crack the plaintext password using brute force techniques. Exploiting this vulnerability requires a valid backend user account. Users are advised to update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described. There are no known workarounds for this issue.

TYPO3 vulnerable to Weak Authentication in Session Handling
TYPO3 is an open source PHP based web content management system released under the GNU GPL. In typo3 installations there are always at least two different sites. Eg. first.example.org and second.example.com. In affected versions a session cookie generated for the first site can be reused on the second site without requiring additional authentication. This vulnerability has been addressed in versions 8.7.55, 9.5.44, 10.4.41, 11.5.33, and 12.4.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cross-site Scripting
TYPO3 contains a cross-site scripting vulnerability. When error messages are not properly encoded, the components `_QueryGenerator_` and `_QueryView_` are vulnerable to both reflected and persistent cross-site scripting. A valid backend user account having administrator privileges is needed to exploit this vulnerability. TYPO3 contain a patch for this issue.

Inclusion of Sensitive Information in Log Files
TYPO3 is an open source PHP based web content management system. User credentials may been logged as plain-text. This occurs when explicitly using log level debug, which is not the default configuration. TYPO3 contain a patch for this vulnerability.

Improper Access Control
TYPO3 is an open source PHP based web content management system released under the GNU GPL. The TYPO3-specific `t3://` URI scheme could be used to access resources outside of the users' permission scope. This encompassed files, folders, pages, and records (although only if a valid link-handling configuration was provided). Exploiting this vulnerability requires a valid backend user account. Users are advised to update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described. There are no known workarounds for this issue.

Improper Access Control
TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions of TYPO3 entities of the File Abstraction Layer (FAL) could be persisted directly via `DataHandler`. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage ("zero-storage") is used as a backward compatibility layer for files located outside properly configured file storages and within the public web root directory. Exploiting this vulnerability requires a valid backend user account. Users are advised to update to TYPO3 version 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, or 13.0.1 which fix the problem described. When persisting entities of the File Abstraction Layer directly via DataHandler, `sys_file` entities are now denied by default, and `sys_file_reference` & `sys_file_metadata` entities are not permitted to reference files in the fallback storage anymore. When importing data from secure origins, this must be explicitly enabled in the corresponding DataHandler instance by using `$dataHandler->isImporting = true;`.

Exposure of Sensitive Information to an Unauthorized Actor
TYPO3 is an open source PHP based web content management system released under the GNU GPL. The plaintext value of `$GLOBALS['SYS']['encryptionKey']` was displayed in the editing forms of the TYPO3 Install Tool user interface. This allowed attackers to utilize the value to generate cryptographic hashes used for verifying the authenticity of HTTP request parameters. Exploiting this vulnerability requires an administrator-level backend user account with system maintainer permissions. Users are advised to update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described. There are no known workarounds for this vulnerability.
