CVE-2016-9465

https://notcve.org/view.php?id=CVE-2016-9465

Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Stored XSS in CardDAV image export. The CardDAV image export functionality as implemented in Nextcloud/ownCloud allows the download of images stored within a vCard. Due to not performing any kind of verification on the image content this is prone to a stored Cross-Site Scripting attack. Nextcloud Server en versiones anteriores a 10.0.1 y ownCloud Server en versiones anteriores a 9.0.6 y 9.1.2 sufren de XSS almacenado en la exportación de imágenes CardDAV. La funcionalidad de exportación de imágenes CardDAV implementada en Nextcloud/ownCloud permite descargar imágenes almacenadas dentro de una vCard. • https://github.com/nextcloud/server/commit/68ab8325c799d20c1fb7e98d670785176590e7d0 https://github.com/owncloud/core/commit/6bf3be3877d9d9fda9c66926fe273fe79cbaf58e https://github.com/owncloud/core/commit/b5a5be24c418033cb2ef965a4f3f06b7b4213845 https://hackerone.com/reports/163338 https://nextcloud.com/security/advisory/?id=nc-sa-2016-008 https://owncloud.org/security/advisory/?id=oc-sa-2016-018 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2016-9461

https://notcve.org/view.php?id=CVE-2016-9461

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files. Nextcloud Server en versiones anteriores a 9.0.52 & ownCloud Server en versiones anteriores a 9.0.4 no están verificando correctamente los permisos de comprobación de edición en las acciones de copia de WebDAV. • http://www.securityfocus.com/bid/97276 https://github.com/nextcloud/server/commit/3491400261c1454a9a30d3ec96969573330120cc https://github.com/owncloud/core/commit/0622e635d97cb17c5e1363e370bb8268cc3d2547 https://github.com/owncloud/core/commit/121a3304a0c37ccda0e1b63ddc528cba9121a36e https://github.com/owncloud/core/commit/acbbadb71ceee7f01da347f7dcd519beda78cc47 https://github.com/owncloud/core/commit/c0a4b7b3f38ad2eaf506484b3b92ec678cb021c9 https://hackerone.com/reports/145950 https://nextcloud.com/security/advisory/?id=nc-sa-2016-004 https:// • CWE-275: Permission Issues CWE-284: Improper Access Control •

CVE-2016-9459

https://notcve.org/view.php?id=CVE-2016-9459

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a log pollution vulnerability potentially leading to a local XSS. The download log functionality in the admin screen is delivering the log in JSON format to the end-user. The file was delivered with an attachment disposition forcing the browser to download the document. However, Firefox running on Microsoft Windows would offer the user to open the data in the browser as an HTML document. Thus any injected data in the log would be executed. • http://www.securityfocus.com/bid/97284 https://github.com/nextcloud/server/commit/94975af6db1551c2d23136c2ea22866a5b416070 https://github.com/owncloud/core/commit/044ee072a647636b1a17c89265c7233b35371335 https://github.com/owncloud/core/commit/b7fa2c5dc945b40bc6ed0a9a0e47c282ebf043e1 https://github.com/owncloud/core/commit/efa35d621dc7ff975468e636a5d1c153511296dc https://hackerone.com/reports/146278 https://nextcloud.com/security/advisory/?id=nc-sa-2016-002 https://owncloud.org/security/advisory?id=oc-sa-2016-012 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-209: Generation of Error Message Containing Sensitive Information •

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a content-spoofing attack in the files app. The location bar in the files app was not verifying the passed parameters. An attacker could craft an invalid link to a fake directory structure and use this to display an attacker-controlled error message to the user. Nextcloud Server en versiones anteriores a 9.0.52 & ownCloud Server en versiones anteriores a 9.0.4 son vulnerables a un ataque de contenido falsificado en la aplicación de archivos.

Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from content spoofing in the dav app. The exception message displayed on the DAV endpoints contained partially user-controllable input leading to a potential misrepresentation of information.
