CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-21359 – Denial of Service in Page Error Handling
https://notcve.org/view.php?id=CVE-2021-21359
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 9.5.25, 10.4.14, 11.1.1 requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This is fixed in versions 9.5.25, 10.4.14, 11.1.1. TYPO3 es un sistema de gestión de contenidos web de código abierto basado en PHP. • https://github.com/TYPO3/TYPO3.CMS/security/advisories/GHSA-4p9g-qgx9-397p https://packagist.org/packages/typo3/cms-core https://typo3.org/security/advisory/typo3-core-sa-2021-005 • CWE-405: Asymmetric Resource Consumption (Amplification) CWE-674: Uncontrolled Recursion •
CVSS: 5.4EPSS: 0%CPEs: 5EXPL: 0CVE-2021-21370 – Cross-Site Scripting in Content Preview (CType menu)
https://notcve.org/view.php?id=CVE-2021-21370
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1 it has been discovered that content elements of type _menu_ are vulnerable to cross-site scripting when their referenced items get previewed in the page module. A valid backend user account is needed to exploit this vulnerability. This is fixed in versions 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1.

CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2021-21339 – Cleartext storage of session identifier
https://notcve.org/view.php?id=CVE-2021-21339
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1 user session identifiers were stored in cleartext - without processing of additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance SQL injection in any other component of the system. This is fixed in versions 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1.

TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 10.4.14, 11.1.1 it has been discovered that database fields used as _descriptionColumn_ are vulnerable to cross-site scripting when their content gets previewed.

CVSS: 8.6EPSS: 0%CPEs: 4EXPL: 0CVE-2021-21355 – Unrestricted File Upload in Form Framework
https://notcve.org/view.php?id=CVE-2021-21355
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 8.7.40, 9.5.25, 10.4.14, 11.1.1, 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_. Besides that, _UploadedFileReferenceConverter_ transforming uploaded files into proper FileReference domain model objects handles possible file uploads for other extensions as well - given those extensions use the Extbase MVC framework, make use of FileReference items in their direct or inherited domain model definitions and did not implement their own type converter. In case this scenario applies, _UploadedFileReferenceConverter_ accepts any file mime-type and persists files in 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. • https://github.com/TYPO3/TYPO3.CMS/security/advisories/GHSA-2r6j-862c-m2v2 https://packagist.org/packages/typo3/cms-form https://typo3.org/security/advisory/typo3-core-sa-2021-002 • CWE-434: Unrestricted Upload of File with Dangerous Type CWE-552: Files or Directories Accessible to External Parties •
