| CVE-2021-32703 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 5.3 Medium |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, there was a lack of ratelimiting on the shareinfo endpoint. This may have allowed an attacker to enumerate potentially valid share tokens. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. | ||||
| CVE-2021-32688 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 8.8 High |
| Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server supports application specific tokens for authentication purposes. These tokens are supposed to be granted to a specific applications (e.g. DAV sync clients), and can also be configured by the user to not have any filesystem access. Due to a lacking permission check, the tokens were able to change their own permissions in versions prior to 19.0.13, 20.0.11, and 21.0.3. Thus fileystem limited tokens were able to grant themselves access to the filesystem. The issue is patched in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds aside from upgrading. | ||||
| CVE-2021-32680 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 3.3 Low |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions priot to 19.0.13, 20.0.11, and 21.0.3, Nextcloud Server audit logging functionality wasn't properly logging events for the unsetting of a share expiration date. This event is supposed to be logged. This issue is patched in versions 19.0.13, 20.0.11, and 21.0.3. | ||||
| CVE-2021-32679 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 3.5 Low |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.0.11, and 21.0.3, filenames where not escaped by default in controllers using `DownloadResponse`. When a user-supplied filename was passed unsanitized into a `DownloadResponse`, this could be used to trick users into downloading malicious files with a benign file extension. This would show in UI behaviours where Nextcloud applications would display a benign file extension (e.g. JPEG), but the file will actually be downloaded with an executable file extension. The vulnerability is patched in versions 19.0.13, 20.0.11, and 21.0.3. Administrators of Nextcloud instances do not have a workaround available, but developers of Nextcloud apps may manually escape the file name before passing it into `DownloadResponse`. | ||||
| CVE-2021-32678 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 3.7 Low |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.0.11, and 21.0.3, ratelimits are not applied to OCS API responses. This affects any OCS API controller (`OCSController`) using the `@BruteForceProtection` annotation. Risk depends on the installed applications on the Nextcloud Server, but could range from bypassing authentication ratelimits or spamming other Nextcloud users. The vulnerability is patched in versions 19.0.13, 20.0.11, and 21.0.3. No workarounds aside from upgrading are known to exist. | ||||
| CVE-2021-32657 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 4.3 Medium |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions of Nextcloud Server prior to 10.0.11, 20.0.10, and 21.0.2, a malicious user may be able to break the user administration page. This would disallow administrators to administrate users on the Nextcloud instance. The vulnerability is fixed in versions 19.0.11, 20.0.10, and 21.0.2. As a workaround, administrators can use the OCC command line tool to administrate the Nextcloud users. | ||||
| CVE-2021-32656 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 8.6 High |
| Nextcloud Server is a Nextcloud package that handles data storage. A vulnerability in federated share exists in versions prior to 19.0.11, 20.0.10, and 21.0.2. An attacker can gain access to basic information about users of a server by accessing a public link that a legitimate server user added as a federated share. This happens because Nextcloud supports sharing registered users with other Nextcloud servers, which can be done automatically when selecting the "Add server automatically once a federated share was created successfully" setting. The vulnerability is patched in versions 19.0.11, 20.0.10, and 21.0.2 As a workaround, disable "Add server automatically once a federated share was created successfully" in the Nextcloud settings. | ||||
| CVE-2021-32655 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 3.5 Low |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.11, 20.0.10, and 21.0.2, an attacker is able to convert a Files Drop link to a federated share. This causes an issue on the UI side of the sharing user. When the sharing user opens the sharing panel and tries to remove the "Create" privileges of this unexpected share, Nextcloud server would silently grant the share read privileges. The vulnerability is patched in versions 19.0.11, 20.0.10 and 21.0.2. No workarounds are known to exist. | ||||
| CVE-2021-32654 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 8.1 High |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.11, 20.0.10, and 21.0.2, an attacker is able to receive write/read privileges on any Federated File Share. Since public links can be added as federated file share, this can also be exploited on any public link. Users can upgrade to patched versions (19.0.11, 20.0.10 or 21.0.2) or, as a workaround, disable federated file sharing. | ||||
| CVE-2021-32653 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 2.7 Low |
| Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server versions prior to 19.0.11, 20.0.10, or 21.0.2 send user IDs to the lookup server even if the user has no fields set to published. The vulnerability is patched in versions 19.0.11, 20.0.10, and 21.0.2; no workarounds outside the updates are known to exist. | ||||
| CVE-2021-22915 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 9.8 Critical |
| Nextcloud server before 19.0.11, 20.0.10, 21.0.2 is vulnerable to brute force attacks due to lack of inclusion of IPv6 subnets in rate-limiting considerations. This could potentially result in an attacker bypassing rate-limit controls such as the Nextcloud brute-force protection. | ||||
| CVE-2021-22878 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 4.8 Medium |
| Nextcloud Server prior to 20.0.6 is vulnerable to reflected cross-site scripting (XSS) due to lack of sanitization in `OC.Notification.show`. | ||||
| CVE-2021-22877 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 6.5 Medium |
| A missing user check in Nextcloud prior to 20.0.6 inadvertently populates a user's own credentials for other users external storage configuration when not already configured yet. | ||||
| CVE-2020-8296 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 6.7 Medium |
| Nextcloud Server prior to 20.0.0 stores passwords in a recoverable format even when external storage is not configured. | ||||
| CVE-2020-8295 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 7.5 High |
| A wrong check in Nextcloud Server 19 and prior allowed to perform a denial of service attack when resetting the password for a user. | ||||
| CVE-2020-8294 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 5.4 Medium |
| A missing link validation in Nextcloud Server before 20.0.2, 19.0.5, 18.0.11 allows execution of a stored XSS attack using Internet Explorer when saving a 'javascript:' URL in markdown format. | ||||
| CVE-2020-8293 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 6.5 Medium |
| A missing input validation in Nextcloud Server before 20.0.2, 19.0.5, 18.0.11 allows users to store unlimited data in workflow rules causing load and potential DDoS on later interactions and usage with those rules. | ||||
| CVE-2020-8259 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 8.1 High |
| Insufficient protection of the server-side encryption keys in Nextcloud Server 19.0.1 allowed an attacker to replace the encryption keys. | ||||
| CVE-2020-8236 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 6.8 Medium |
| A wrong configuration in Nextcloud Server 19.0.1 incorrectly made the user feel the passwordless WebAuthn is also a two factor verification by asking for the PIN of the passwordless WebAuthn but not verifying it. | ||||
| CVE-2020-8223 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2024-11-21 | 6.5 Medium |
| A logic error in Nextcloud Server 19.0.0 caused a privilege escalation allowing malicious users to reshare with higher permissions than they got assigned themselves. | ||||
