CVE-2018-3781 1 Nextcloud 1 Talk 2024-02-04 3.5 LOW 5.4 MEDIUM
A missing sanitization of search results for an autocomplete field in NextCloud Talk <3.2.5 could lead to a stored XSS requiring user-interaction. The missing sanitization only affected user names, hence malicious search results could only be crafted by authenticated users.

A bug causing session fixation in Nextcloud Server prior to 14.0.0, 13.0.3 and 12.0.8 could potentially allow an attacker to obtain access to password protected shares.
CVE-2018-3775 1 Nextcloud 1 Nextcloud Server 2024-02-04 4.0 MEDIUM 8.8 HIGH
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-2018-16467 1 Nextcloud 1 Nextcloud Server 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
A missing check in Nextcloud Server prior to 14.0.0 could give unauthorized access to the previews of single file password protected shares.
CVE-2018-16464 1 Nextcloud 1 Nextcloud Server 2024-02-04 3.5 LOW 5.7 MEDIUM

Improper input validator in Nextcloud Server prior to 12.0.3 and 11.0.5 could lead to an attacker's actions not being logged in the audit log.
CVE-2018-16466 1 Nextcloud 1 Nextcloud Server 2024-02-04 5.5 MEDIUM 8.1 HIGH
Improper revalidation of permissions in Nextcloud Server prior to 14.0.0, 13.0.6 and 12.0.11 lead to not accepting access restrictions by acess tokens.
CVE-2018-16465 1 Nextcloud 1 Nextcloud Server 2024-02-04 4.3 MEDIUM 5.3 MEDIUM
Missing state in Nextcloud Server prior to 14.0.0 would not enforce the use of a second factor at login if the the provider of the second factor failed to load.
CVE-2018-3762 1 Nextcloud 1 Nextcloud Server 2024-02-04 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-2018-3763 1 Nextcloud 1 Calendar 2024-02-04 3.5 LOW 4.8 MEDIUM
In Nextcloud Calendar before 1.5.8 and 1.6.1, a missing sanitization of search results for an autocomplete field could lead to a stored XSS requiring user-interaction. The missing sanitization only affected group names, hence malicious search results could only be crafted by privileged users like admins or group admins.
CVE-2017-0936 1 Nextcloud 1 Nextcloud Server 2024-02-04 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 2024-02-04 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-2018-3764 1 Nextcloud 1 Contacts 2024-02-04 3.5 LOW 4.8 MEDIUM
In Nextcloud Contacts before 2.1.2, a missing sanitization of search results for an autocomplete field could lead to a stored XSS requiring user-interaction. The missing sanitization only affected group names, hence malicious search results could only be crafted by privileged users like admins or group admins.
CVE-2016-9461 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2024-02-04 4.0 MEDIUM 4.3 MEDIUM
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.
CVE-2016-9468 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2024-02-04 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-2016-9462 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2024-02-04 4.0 MEDIUM 4.3 MEDIUM
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.
CVE-2016-9463 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2024-02-04 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-2017-0893 1 Nextcloud 1 Nextcloud Server 2024-02-04 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-2017-0885 1 Nextcloud 1 Nextcloud 2024-02-04 4.0 MEDIUM 4.3 MEDIUM
Nextcloud Server before 9.0.55 and 10.0.2 suffers from a error message disclosing existence of file in write-only share. Due to an error in the application logic an adversary with access to a write-only share may enumerate the names of existing files and subfolders by comparing the exception messages.
CVE-2016-9460 2 Nextcloud, Owncloud 2 Nextcloud, Owncloud 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a content-spoofing attack 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.
