Improper Authentication in Nextcloud Server prior to version 12.0.3 would allow an attacker that obtained user credentials to bypass the 2 Factor Authentication.
CVE-2018-3762 1 Nextcloud 1 Nextcloud Server 2023-12-10 4.0 MEDIUM 4.3 MEDIUM
Nextcloud Server before 12.0.8 and 13.0.3 suffers from improper checks of dropped permissions for incoming shares allowing a user to still request previews for files it should not have access to.
CVE-2017-0936 1 Nextcloud 1 Nextcloud Server 2023-12-10 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-2018-3761 1 Nextcloud 1 Nextcloud Server 2023-12-10 5.8 MEDIUM 8.1 HIGH
Nextcloud Server before 12.0.8 and 13.0.3 suffer from improper authentication on the OAuth2 token endpoint. Missing checks potentially allowed handing out new tokens in case the OAuth2 client was partly compromised.
CVE-2017-0890 1 Nextcloud 1 Nextcloud Server 2023-12-10 3.5 LOW 5.4 MEDIUM
Nextcloud Server before 11.0.3 is vulnerable to an inadequate escaping leading to a XSS vulnerability in the search module. To be exploitable a user has to write or paste malicious content into the search dialogue.
CVE-2017-0892 1 Nextcloud 1 Nextcloud Server 2023-12-10 4.3 MEDIUM 3.5 LOW
Nextcloud Server before 11.0.3 is vulnerable to an improper session handling allowed an application specific password without permission to the files access to the users file.
CVE-2016-9464 1 Nextcloud 1 Nextcloud Server 2023-12-10 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.
CVE-2017-0895 1 Nextcloud 1 Nextcloud Server 2023-12-10 3.5 LOW 3.5 LOW
Nextcloud Server before 10.0.4 and 11.0.2 are vulnerable to disclosure of calendar and addressbook names to other logged-in users. Note that no actual content of the calendar and addressbook has been disclosed.
CVE-2017-0893 1 Nextcloud 1 Nextcloud Server 2023-12-10 3.5 LOW 5.4 MEDIUM
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-2016-9463 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2023-12-10 6.8 MEDIUM 8.1 HIGH
Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.1.2, 9.0.6, and 8.2.9 suffer from SMB User Authentication Bypass. Nextcloud/ownCloud include an optional and not by default enabled SMB authentication component that allows authenticating users against an SMB server. This backend is implemented in a way that tries to connect to a SMB server and if that succeeded consider the user logged-in. The backend did not properly take into account SMB servers that have any kind of anonymous auth configured. This is the default on SMB servers nowadays and allows an unauthenticated attacker to gain access to an account without valid credentials. Note: The SMB backend is disabled by default and requires manual configuration in the Nextcloud/ownCloud config file. If you have not configured the SMB backend then you're not affected by this vulnerability.
CVE-2016-9467 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2023-12-10 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-2016-9459 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2023-12-10 4.3 MEDIUM 6.1 MEDIUM
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.
