Nextcloud Server before 9.0.55 and 10.0.2 suffers from a bypass in the quota limitation. Due to not properly sanitizing values provided by the `OC-Total-Length` HTTP header an authenticated adversary may be able to exceed their configured user quota. Thus using more space than allowed by the administrator. Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 Sufre una evasión en la limitación de cuota. Debido a que no se desinfectan correctamente los valores proporcionados por la cabecera "OC-Total-Length" HTTP, un adversario autenticado puede superar su cuota de usuario configurada. • https://hackerone.com/reports/173622 https://nextcloud.com/security/advisory/?id=nc-sa-2017-005 • CWE-20: Improper Input Validation CWE-807: Reliance on Untrusted Inputs in a Security Decision •

Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Reflected XSS in the Gallery application. The gallery app was not properly sanitizing exception messages from the Nextcloud/ownCloud server. Due to an endpoint where an attacker could influence the error message, this led to a reflected Cross-Site-Scripting vulnerability. 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 Reflexed XSS en la aplicación Galería. La aplicación de la galería no estaba correctamente desinfectando los mensajes de excepción del servidor Nextcloud/ownCloud. • https://github.com/nextcloud/gallery/commit/f9ef505c1d60c9041e251682e0f6b3daad952d58 https://github.com/owncloud/gallery/commit/b3b3772fb9bec61ba10d357bef42b676fa474eee https://github.com/owncloud/gallery/commit/dc4887f1afcc0cf304f4a0694075c9364298ad8a https://hackerone.com/reports/165686 https://nextcloud.com/security/advisory/?id=nc-sa-2016-009 https://owncloud.org/security/advisory/?id=oc-sa-2016-019 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

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 9.0.54 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 •
