Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions. Nextcloud Server en versiones anteriores a 9.0.52 & ownCloud Server en versiones anteriores a 9.0.4 no están verificando correctamente los privilegios de restauración al restaurar un archivo. La capacidad de restauración de Nextcloud/ownCloud no estaba verificando si un usuario sólo tiene acceso de sólo lectura a un recurso compartido. • http://www.securityfocus.com/bid/97285 https://github.com/nextcloud/server/commit/1208953ba1d4d55a18a639846bbcdd66a2d5bc5e https://github.com/owncloud/core/commit/23383080731d092e079986464a8c4c9ffcb79f4c https://github.com/owncloud/core/commit/3b056fa68ce502ceb0db9b446dab3b9e7b10dd13 https://github.com/owncloud/core/commit/c93eca49c32428ece03dd67042772d5fa62c8d6e https://github.com/owncloud/core/commit/d31720b6f1e8c8dfeb5e8805ab35ad7c8000b2f1 https://hackerone.com/reports/146067 https://nextcloud.com/security/advisory/?id=nc-sa-2016-005 https:// • CWE-275: Permission Issues CWE-284: Improper Access Control •

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') •

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 •

Nextcloud Server before 9.0.54 and 10.0.0 suffers from an improper authorization check on removing shares. The Sharing Backend as implemented in Nextcloud does differentiate between shares to users and groups. In case of a received group share, users should be able to unshare the file to themselves but not to the whole group. The previous API implementation simply unshared the file to all users in the group. Nextcloud Server en versiones anteriores a 9.0.54 y 10.0.0 sufre de una verificación de autorización incorrecta de los recursos eliminados. • http://www.securityfocus.com/bid/97287 https://github.com/nextcloud/server/commit/3387e5d00fcf6b2ea6b285a091e5743f545e7202 https://github.com/nextcloud/server/commit/7289cb5ec0b812992ab0dfb889744b94bc0994f0 https://github.com/nextcloud/server/commit/a5471b4a3e3f30e99e4de39c97c0c3b3c2f1618f https://github.com/nextcloud/server/commit/e2c4f4f9aa11bc92e8f2212cce73841b922187e8 https://hackerone.com/reports/153905 https://nextcloud.com/security/advisory/?id=nc-sa-2016-007 • CWE-285: Improper Authorization •

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 •
