"Typo3 News :

CVE-2020-11063: TYPO3-CORE-SA-2020-001: Information Disclosure in
Password Reset

It has been discovered that time-based attacks can be used with the
password reset functionality for backend users. This allows an
attacker to verify whether a backend user account with a given email
address exists or not.

CVE-2020-11064: TYPO3-CORE-SA-2020-002: Cross-Site Scripting in Form
Engine

It has been discovered that HTML placeholder attributes containing
data of other database records are vulnerable to cross-site scripting.
A valid backend user account is needed to exploit this vulnerability.

CVE-2020-11065: TYPO3-CORE-SA-2020-003: Cross-Site Scripting in Link
Handling

It has been discovered that link tags generated by typolink
functionality are vulnerable to cross-site scripting - properties
being assigned as HTML attributes have not been parsed correctly.

CVE-2020-11066: TYPO3-CORE-SA-2020-004: Class destructors causing
side-effects when being unserialized

Calling unserialize() on malicious user-submitted content can result
in the following scenarios :

- trigger deletion of arbitrary directory in file system (if writable
for web server)

- trigger message submission via email using identity of website
(mail relay)

Another insecure deserialization vulnerability is required to actually
exploit mentioned aspects.

CVE-2020-11067: TYPO3-CORE-SA-2020-005: Insecure Deserialization in
Backend User Settings

It has been discovered that backend user settings (in $BE_USER->uc)
are vulnerable to insecure deserialization. In combination with
vulnerabilities of 3rd party components this can lead to remote code
execution. A valid backend user account is needed to exploit this
vulnerability.

CVE-2020-11069: TYPO3-CORE-SA-2020-006: Same-Site Request Forgery to
Backend User Interface

It has been discovered that the backend user interface and install
tool are vulnerable to same-site request forgery. A backend user can
be tricked into interacting with a malicious resource an attacker
previously managed to upload to the web server - scripts are then
executed with the privileges of the victims' user session.

In a worst case scenario new admin users can be created which can
directly be used by an attacker. The vulnerability is basically a
cross-site request forgery (CSRF) triggered by a cross-site scripting
vulnerability (XSS) - but happens on the same target host - thus,
it' actually a same-site request forgery (SSRF).

Malicious payload such as HTML containing JavaScript might be provided
by either an authenticated backend user or by a non-authenticated user
using a 3rd party extension - e.g. file upload in a contact form with
knowing the target location.

The attacked victim requires an active and valid backend or install
tool user session at the time of the attack to be successful.");
