Nextcloud Server before 9.0.58 and 10.0.5 and 11.0.3 are shipping a vulnerable JavaScript library for sanitizing untrusted user-input which suffered from a XSS vulnerability caused by a behaviour change in Safari 10.1 and 10.2. Note that Nextcloud employs a strict Content-Security-Policy preventing exploitation of this XSS issue on modern web browsers.
CVE-2017-0891 1 Nextcloud 1 Nextcloud Server 2019-10-09 3.5 LOW 5.4 MEDIUM
Nextcloud Server before 9.0.58 and 10.0.5 and 11.0.3 are vulnerable to an inadequate escaping of error messages leading to XSS vulnerabilities in multiple components.
CVE-2017-0883 1 Nextcloud 1 Nextcloud Server 2019-10-09 5.5 MEDIUM 6.4 MEDIUM
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.
CVE-2017-0936 1 Nextcloud 1 Nextcloud Server 2019-10-09 4.9 MEDIUM 5.7 MEDIUM
Nextcloud Server before 11.0.7 and 12.0.5 suffers from an Authorization Bypass Through User-Controlled Key vulnerability. A missing ownership check allowed logged-in users to change the scope of app passwords of other users. Note that the app passwords themselves where neither disclosed nor could the error be misused to identify as another user.
CVE-2016-9468 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2019-10-09 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2016-9467 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2019-10-09 5.0 MEDIUM 5.3 MEDIUM
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 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.
CVE-2016-9466 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2019-10-09 4.3 MEDIUM 6.1 MEDIUM
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.
CVE-2016-9465 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2019-10-09 3.5 LOW 5.4 MEDIUM
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.
CVE-2016-9464 1 Nextcloud 1 Nextcloud Server 2019-10-09 4.0 MEDIUM 4.3 MEDIUM
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.
