CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 1CVE-2022-22690 – Umbraco Remote ApplicationURL Overwrite
https://notcve.org/view.php?id=CVE-2022-22690
Within the Umbraco CMS, a configuration element named "UmbracoApplicationUrl" (or just "ApplicationUrl") is used whenever application code needs to build a URL pointing back to the site. For example, when a user resets their password and the application builds a password reset URL or when the administrator invites users to the site. For Umbraco versions less than 9.2.0, if the Application URL is not specifically configured, the attacker can manipulate this value and store it persistently affecting all users for components where the "UmbracoApplicationUrl" is used. For example, the attacker is able to change the URL users receive when resetting their password so that it points to the attackers server, when the user follows this link the reset token can be intercepted by the attacker resulting in account takeover. Dentro del CMS Umbraco, un elemento de configuración llamado "UmbracoApplicationUrl" (o simplemente "ApplicationUrl") es usado siempre que el código de la aplicación necesita construir una URL que apunte al sitio. • https://appcheck-ng.com/umbraco-applicationurl-overwrite-persistent-password-reset-poison-cve-2022-22690-cve-2022-22691 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 7.4EPSS: 0%CPEs: 1EXPL: 1CVE-2022-22691 – Umbraco Password Reset URL Poison
https://notcve.org/view.php?id=CVE-2022-22691
The password reset component deployed within Umbraco uses the hostname supplied within the request host header when building a password reset URL. It may be possible to manipulate the URL sent to Umbraco users when so that it points to the attackers server thereby disclosing the password reset token if/when the link is followed. A related vulnerability (CVE-2022-22690) could allow this flaw to become persistent so that all password reset URLs are affected persistently following a successful attack. See the AppCheck advisory for further information and associated caveats. El componente de restablecimiento de contraseñas desplegado en Umbraco usa el nombre de host suministrado dentro del encabezado de host de la petición cuando construye una URL de restablecimiento de contraseñas. • https://appcheck-ng.com/umbraco-applicationurl-overwrite-persistent-password-reset-poison-cve-2022-22690-cve-2022-22691 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') CWE-640: Weak Password Recovery Mechanism for Forgotten Password •
CVSS: 9.8EPSS: 2%CPEs: 16EXPL: 0CVE-2021-37334
https://notcve.org/view.php?id=CVE-2021-37334
Umbraco Forms version 4.0.0 up to and including 8.7.5 and below are vulnerable to a security flaw that could lead to a remote code execution attack and/or arbitrary file deletion. A vulnerability occurs because validation of the file extension is performed after the file has been stored in a temporary directory. By default, files are stored within the application directory structure at %BASEDIR%/APP_DATA/TEMP/FileUploads/. Whilst access to this directory is restricted by the root web.config file, it is possible to override this restriction by uploading another specially crafted web.config file to the temporary directory. It is possible to exploit this flaw to upload a malicious script file to execute arbitrary code and system commands on the server. • https://umbraco.com/blog/security-advisory-20th-of-july-2021-patch-is-now-available https://umbraco.com/blog/security-advisory-security-patches-for-umbraco-forms-ready-on-july-20th-2021-at-7-am-utc •
