https://notcve.org/view.php?id=CVE-2017-0883
Nextcloud Server before 9.0.55 and 10.0.2 suffers from a permission increase on re-sharing via OCS API issue. A permission related issue within the OCS sharing API allowed an authenticated adversary to reshare shared files with an increasing permission set. This may allow an attacker to edit files in a share despite having only a 'read' permission set. Note that this only affects folders and files that the adversary has at least read-only permissions for. Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 sufre un aumento de permiso al volver a compartir a través del problema de la API de OCS compartiendo API permitió a un adversario autenticado compartir archivos compartidos con un conjunto de permisos creciente. • https://hackerone.com/reports/169680 https://nextcloud.com/security/advisory/?id=nc-sa-2017-001 • CWE-275: Permission Issues CWE-732: Incorrect Permission Assignment for Critical Resource •

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.

https://notcve.org/view.php?id=CVE-2016-9462
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 •
