| CVE-2021-32734 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-26 | 5.0 MEDIUM | 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, the Nextcloud Text application shipped with Nextcloud Server returned verbatim exception messages to the user. This could result in a full path disclosure on shared files. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. As a workaround, one may disable the Nextcloud Text application in Nextcloud Server app settings. | |||||
| CVE-2021-32725 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-26 | 5.0 MEDIUM | 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, default share permissions were not being respected for federated reshares of files and folders. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. | |||||
| CVE-2021-32679 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2022-10-26 | 6.8 MEDIUM | 8.8 HIGH |
| 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-2021-32705 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2022-10-26 | 5.0 MEDIUM | 7.5 HIGH |
| 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 public DAV endpoint. This may have allowed an attacker to enumerate potentially valid share tokens or credentials. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. | |||||
| CVE-2021-32703 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2022-10-26 | 5.0 MEDIUM | 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-2021-32680 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2022-10-26 | 2.1 LOW | 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-2021-32688 | 2 Fedoraproject, Nextcloud | 2 Fedora, Nextcloud Server | 2022-10-26 | 7.5 HIGH | 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-2021-32654 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-26 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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 | 2022-10-26 | 4.0 MEDIUM | 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-2021-32655 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-26 | 3.5 LOW | 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-2022-24889 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 4.3 MEDIUM | 4.3 MEDIUM |
| Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Prior to versions 21.0.8, 22.2.4, and 23.0.1, it is possible to trick administrators into enabling "recommended" apps for the Nextcloud server that they do not need, thus expanding their attack surface unnecessarily. This issue is fixed in versions 21.0.8 , 22.2.4, and 23.0.1. | |||||
| CVE-2022-24888 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 5.0 MEDIUM | 4.3 MEDIUM |
| Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Prior to versions 20.0.14.4, 21.0.8, 22.2.4, and 23.0.1, it is possible to create files and folders that have leading and trailing \n, \r, \t, and \v characters. The server rejects files and folders that have these characters in the middle of their names, so this might be an opportunity for injection. This issue is fixed in versions 20.0.14.4, 21.0.8, 22.2.4, and 23.0.1. There are currently no known workarounds. | |||||
| CVE-2022-24741 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 4.3 MEDIUM | 6.5 MEDIUM |
| Nextcloud server is an open source, self hosted cloud style services platform. In affected versions an attacker can cause a denial of service by uploading specially crafted files which will cause the server to allocate too much memory / CPU. It is recommended that the Nextcloud Server is upgraded to 21.0.8 , 22.2.4 or 23.0.1. Users unable to upgrade should disable preview generation with the `'enable_previews'` config flag. | |||||
| CVE-2021-41241 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 4.0 MEDIUM | 4.3 MEDIUM |
| Nextcloud server is a self hosted system designed to provide cloud style services. The groupfolders application for Nextcloud allows sharing a folder with a group of people. In addition, it allows setting "advanced permissions" on subfolders, for example, a user could be granted access to the groupfolder but not specific subfolders. Due to a lacking permission check in affected versions, a user could still access these subfolders by copying the groupfolder to another location. It is recommended that the Nextcloud Server is upgraded to 20.0.14, 21.0.6 or 22.2.1. Users unable to upgrade should disable the "groupfolders" application in the admin settings. | |||||
| CVE-2021-32656 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 5.0 MEDIUM | 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-2021-32726 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-25 | 7.5 HIGH | 9.8 CRITICAL |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, webauthn tokens were not deleted after a user has been deleted. If a victim reused an earlier used username, the previous user could gain access to their account. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. | |||||
| CVE-2021-41239 | 1 Nextcloud | 1 Nextcloud Server | 2022-10-24 | 5.0 MEDIUM | 5.3 MEDIUM |
| Nextcloud server is a self hosted system designed to provide cloud style services. In affected versions the User Status API did not consider the user enumeration settings by the administrator. This allowed a user to enumerate other users on the instance, even when user listings where disabled. It is recommended that the Nextcloud Server is upgraded to 20.0.14, 21.0.6 or 22.2.1. There are no known workarounds. | |||||
| CVE-2017-0888 | 1 Nextcloud | 2 Nextcloud, Nextcloud Server | 2022-10-06 | 4.3 MEDIUM | 4.3 MEDIUM |
| Nextcloud Server before 9.0.55 and 10.0.2 suffers from a Content-Spoofing vulnerability in the "files" app. The top navigation bar displayed in the files list contained partially user-controllable input leading to a potential misrepresentation of information. | |||||
