Unrestricted File Upload in Form Framework ### Problem Due to the lack of ensuring file extensions belong to configured allowed mime-types, attackers can upload arbitrary data with arbitrary file extensions - however, default _fileDenyPattern_ successfully blocked files like _.htaccess_ or _malicious.php_. TYPO3 Extbase extensions, which implement a file upload and do not implement a custom _TypeConverter_ to transform uploaded files into _FileReference_ domain model objects are affected by the vulnerability as well, since the _UploadedFileReferenceConverter_ of _ext:form_ handles the file upload and will accept files of any mime-type which are persisted to the default location. In any way, uploaded files are placed in the default location _/fileadmin/user_upload/_, in most scenarios keeping the submitted filename - which allows attackers to directly reference files, or even correctly guess filenames used by other individuals, disclosing this information. No authentication is required to exploit this vulnerability. ### Solution Update to TYPO3 versions 8.7.40, 9.5.25, 10.4.14, 11.1.1 that fix the problem described. Type converter _UploadedFileReferenceConverter_ is not registered globally anymore and just handles uploaded files within the scope of the Form Framework. Guessable storage location has changed from _/fileadmin/user_upload/form\_\<random-hash\>/_ to _/fileadmin/form_uploads/<random-40-bit>_. Allowed mime-types must match expected file extensions (e.g. _application/pdf_ must be _.pdf_, and cannot be _.html_). Extbase extensions, who rely on the global availability of the _UploadedFileReferenceConverter_ must now implement a custom _TypeConverter_ to handle file uploads or explicitly implement the ext:form _UploadedFileReferenceConverter_ with appropriate setting for accepted mime-types. ### Credits Thanks to Sebastian Michaelsen, Marc Lindemann, Oliver Eglseder, Markus Volkmer, Jakob Kunzmann, Johannes Regner, Richie Lee who reported this issue, and to TYPO3 core & security team members Oliver Hader & Benni Mack, as well as TYPO3 contributor Ralf Zimmermann who fixed the issue. ### References * [TYPO3-CORE-SA-2021-002](https://typo3.org/security/advisory/typo3-core-sa-2021-002) |

TYPO3 Possible Insecure Deserialization in Extbase Request Handling It has been discovered that request handling in Extbase can be vulnerable to insecure deserialization. User submitted payload has to be signed with a corresponding HMAC-SHA1 using the sensitive TYPO3 encryptionKey as secret - invalid or unsigned payload is not deserialized. However, since sensitive information could have been leaked by accident (e.g. in repositories or in commonly known and unprotected backup files), there is the possibility that attackers know the private encryptionKey and are able to calculate the required HMAC-SHA1 to allow a malicious payload to be deserialized. Requirements for successfully exploiting this vulnerability (all of the following): - rendering at least one Extbase plugin in the frontend - encryptionKey has been leaked (from LocalConfiguration.php or corresponding .env file) |

TYPO3 is vulnerable to Cross-Site Scripting via frontend rendering > ### CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:L/E:F/RL:O/RC:C` (8.2) ### Problem TYPO3 core component `GeneralUtility::getIndpEnv()` uses the unfiltered server environment variable `PATH_INFO`, which allows attackers to inject malicious content. In combination with the TypoScript setting [`config.absRefPrefix=auto`](https://github.com/TYPO3/typo3/blob/v11.5.22/typo3/sysext/frontend/Classes/Controller/TypoScriptFrontendController.php#L2547-L2549), attackers can inject malicious HTML code into pages that have not yet been rendered and cached. As a result, injected values would be cached and delivered to other website visitors (persisted cross-site scripting). Individual code which relies on the resolved value of [`GeneralUtility::getIndpEnv('SCRIPT_NAME')`](https://github.com/TYPO3/typo3/blob/v11.5.22/typo3/sysext/core/Classes/Utility/GeneralUtility.php#L2481-L2484) and corresponding usages (as shown below) are vulnerable as well. - `GeneralUtility::getIndpEnv('PATH_INFO') ` - `GeneralUtility::getIndpEnv('SCRIPT_NAME') ` - `GeneralUtility::getIndpEnv('TYPO3_REQUEST_DIR')` - `GeneralUtility::getIndpEnv('TYPO3_REQUEST_SCRIPT')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_PATH')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_SCRIPT')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_URL')` Installations of TYPO3 versions 8.7 and 9.x are probably only affected when server environment variable [`TYPO3_PATH_ROOT`](https://docs.typo3.org/m/typo3/reference-coreapi/9.5/en-us/ApiOverview/Environment/Index.html#configuring-environment-paths) is defined - which is the case if they were installed via Composer. Additional investigations confirmed that Apache and Microsoft IIS web servers using PHP-CGI (FPM, FCGI/FastCGI, or similar) are affected. There might be the risk that nginx is vulnerable as well. It was not possible to exploit Apache/mod_php scenarios. ### Solution The usage of server environment variable `PATH_INFO` has been removed from corresponding processings in `GeneralUtility::getIndpEnv()`. Besides that, the public property `TypoScriptFrontendController::$absRefPrefix` is encoded for both being used as a URI component and for being used as a prefix in an HTML context. This mitigates the cross-site scripting vulnerability. Update to TYPO3 versions 8.7.51 ELTS, 9.5.40 ELTS, 10.4.36 LTS, 11.5.23 LTS and 12.2.0 that fix the problem described above. > ℹ️ **Strong security defaults - Manual actions required** > Any web server using PHP-CGI (FPM, FCGI/FastCGI, or similar) needs to ensure that the PHP setting [**`cgi.fix_pathinfo=1`**](https://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo) is used, which is the default PHP setting. In case this setting is not enabled, an exception is thrown to avoid continuing with invalid path information. For websites that cannot be patched timely the TypoScript setting [`config.absRefPrefix`](https://docs.typo3.org/m/typo3/reference-typoscript/main/en-us/Setup/Config/Index.html#absrefprefix) at least should be set to a static path value, instead of using `auto` - e.g. `config.absRefPrefix=/` - this **does not fix all aspects of the vulnerability**, and is just considered to be an intermediate mitigation to the most prominent manifestation. ### References * [TYPO3-CORE-SA-2023-001](https://typo3.org/security/advisory/typo3-core-sa-2023-001) * [TYPO3-CORE-PSA-2023-001](https://typo3.org/security/advisory/typo3-psa-2023-001) *pre-announcement* |

Cross-Site Scripting via Rich-Text Content > ### Meta > * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC` (5.7) ### Problem Failing to properly parse, sanitize and encode malicious rich-text content, the content rendering process in the website frontend is vulnerable to cross-site scripting. Corresponding rendering instructions via TypoScript functionality _[HTMLparser](https://docs.typo3.org/m/typo3/reference-typoscript/10.4/en-us/Functions/Htmlparser.html)_ do not consider all potentially malicious HTML tag & attribute combinations per default. In addition, the lack of comprehensive default node configuration for rich-text fields in the backend user interface fosters this malfunction. 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. ### Solution Update to TYPO3 versions 7.6.53 ELTS, 8.7.42 ELTS, 9.5.29, 10.4.19, 11.3.2 that fix the problem described above. Custom package _[typo3/html-sanitizer](https://github.com/TYPO3/html-sanitizer)_ - based on allow-lists only - takes care of sanitizing potentially malicious markup. The default behavior is based on safe and commonly used markup - however, this can be extended or restricted further in case it is necessary for individual scenarios. During the frontend rendering process, sanitization is applied to the default TypoScript path `lib.parseFunc`, which is implicitly used by the Fluid view-helper instruction `f:format.html`. Rich-text data persisted using the backend user interface is sanitized as well. Implementation details are explained in corresponding [ChangeLog documentation](https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/9.5.x/Important-94484-IntroduceHTMLSanitizer.html). ### Credits Thanks to Benjamin Stiber, Gert-Jan Jansma, Gábor Ács-Kurucz, Alexander Kellner, Richie Lee, Nina Rösch who reported this issue, and to TYPO3 security team member Oliver Hader, as well as TYPO3 contributor Susanne Moog who fixed the issue. ### References * [TYPO3-CORE-SA-2021-013](https://typo3.org/security/advisory/typo3-core-sa-2021-013) |

Broken Access Control in Form Framework ### Problem Due to improper input validation, attackers can by-pass restrictions of predefined options and submit arbitrary data in the Form Designer backend module of the Form Framework. In the default configuration of the Form Framework this allows attackers to explicitly allow arbitrary mime-types for file uploads - however, default _fileDenyPattern_ successfully blocked files like _.htaccess_ or _malicious.php_. Besides that, attackers can persist those files in any writable directory of the corresponding TYPO3 installation. A valid backend user account with access to the form module is needed to exploit this vulnerability. ### Solution Update to TYPO3 versions 8.7.40, 9.5.25, 10.4.14, 11.1.1 that fix the problem described. ### Credits Thanks to Richie Lee who reported this issue and to TYPO3 contributor Ralf Zimmermann who fixed the issue. ### References * [TYPO3-CORE-SA-2021-003](https://typo3.org/security/advisory/typo3-core-sa-2021-003) |

TYPO3 vulnerable to Improper Access Control Persisting File Abstraction Layer Entities via Data Handler ### Problem 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. ### 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. #### ℹ️ Strong security defaults - Manual actions required 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;`. ### Credits Thanks to TYPO3 core & security team member Oliver Hader who reported and fixed the issue. ### References * [TYPO3-CORE-SA-2024-006](https://typo3.org/security/advisory/typo3-core-sa-2024-006) |

TYPO3 CMS vulnerable to User Enumeration via Response Timing > ### Meta > * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:F/RL:O/RC:C` (4.9) ### Problem It has been discovered that observing response time during user authentication (backend and frontend) can be used to distinguish between existing and non-existing user accounts. Extension authors of 3rd party TYPO3 extensions providing a custom authentication service should check if the extension is affected by the described problem. Affected extensions must implement new `MimicServiceInterface::mimicAuthUser`, which simulates corresponding times regular processing would usually take. ### Solution Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix the problem described above. ### Credits Thanks to Vautia who reported this issue and to TYPO3 core & security team members Oliver Hader who fixed the issue. ### References * [TYPO3-CORE-SA-2022-007](https://typo3.org/security/advisory/typo3-core-sa-2022-007) * [Vulnerability Report on huntr.dev](https://huntr.dev/bounties/7d519735-2877-4fad-bd77-accde3e290a7/) (embargoed +30 days) |

Information Disclosure via Export Module > ### Meta > * CVSS: `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:F/RL:O/RC:C` (4.0) ### Problem The export functionality fails to limit the result set to allowed columns of a particular database table. This allows authenticated users to export internal details of database tables to which they already have access. ### Solution Update to TYPO3 versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.35 ELTS, 10.4.29, 11.5.11 that fix the problem described above. In order to address this issue, access to mentioned export functionality is completely denied for regular backend users. ℹ️ **Strong security defaults - Manual actions required** Following User TSconfig setting would allow using the export functionality for particular users: ``` options.impexp.enableExportForNonAdminUser = 1 ``` ### Credits Thanks to TYPO3 core merger Lina Wolf who reported this issue and to TYPO3 security member Torben Hansen who fixed the issue. ### References * [TYPO3-CORE-SA-2022-001](https://typo3.org/security/advisory/typo3-core-sa-2022-001) |

TYPO3 vulnerable to Improper Access Control of Resources Referenced by t3:// URI Scheme ### Problem The TYPO3-specific [`t3://` URI scheme](https://docs.typo3.org/m/typo3/reference-typoscript/main/en-us/Functions/Typolink.html#resource-references) 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. ### 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 Richie Lee who reported this issue and to TYPO3 core & security team member Benjamin Franzke who fixed the issue. ### References * [TYPO3-CORE-SA-2024-005](https://typo3.org/security/advisory/typo3-core-sa-2024-005) |
