CVE-2021-32695 1 Nextcloud 1 Nextcloud 2022-10-25 4.3 MEDIUM 3.3 LOW
Nextcloud Android app is the Android client for Nextcloud. In versions prior to 3.16.1, a malicious app on the same device could have gotten access to the shared preferences of the Nextcloud Android application. This required user-interaction as a victim had to initiate the sharing flow and choose the malicious app. The shared preferences contain some limited private data such as push tokens and the account name. The vulnerability is patched in version 3.16.1.
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-2021-41181 1 Nextcloud 1 Talk 2022-10-24 2.1 LOW 2.4 LOW
Nextcloud talk is a self hosting messaging service. In versions prior to 12.3.0 the Nextcloud Android Talk application did not properly detect the lockscreen state when a call was incoming. If an attacker got physical access to the locked phone, and the victim received a phone call the attacker could gain access to the chat messages and files of the user. It is recommended that the Nextcloud Android Talk App is upgraded to 12.3.0. 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.
CVE-2017-0886 1 Nextcloud 1 Nextcloud Server 2022-10-04 4.0 MEDIUM 6.5 MEDIUM
Nextcloud Server before 9.0.55 and 10.0.2 suffers from a Denial of Service attack. Due to an error in the application logic an authenticated adversary may trigger an endless recursion in the application leading to a potential Denial of Service.
CVE-2017-0887 1 Nextcloud 1 Nextcloud Server 2022-10-04 4.0 MEDIUM 4.3 MEDIUM
Nextcloud Server before 9.0.55 and 10.0.2 suffers from a bypass in the quota limitation. Due to not properly sanitizing values provided by the `OC-Total-Length` HTTP header an authenticated adversary may be able to exceed their configured user quota. Thus using more space than allowed by the administrator.
CVE-2021-32728 2 Debian, Nextcloud 2 Debian Linux, Desktop 2022-10-04 4.0 MEDIUM 6.5 MEDIUM
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with a computer. Clients using the Nextcloud end-to-end encryption feature download the public and private key via an API endpoint. In versions prior to 3.3.0, the Nextcloud Desktop client fails to check if a private key belongs to previously downloaded public certificate. If the Nextcloud instance serves a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. This issue is fixed in Nextcloud Desktop Client version 3.3.0. There are no known workarounds aside from upgrading.
CVE-2017-0884 1 Nextcloud 1 Nextcloud Server 2022-10-04 4.0 MEDIUM 4.3 MEDIUM
Nextcloud Server before 9.0.55 and 10.0.2 suffers from a creation of folders in read-only folders despite lacking permissions issue. Due to a logical error in the file caching layer an authenticated adversary is able to create empty folders inside a shared folder. Note that this only affects folders and files that the adversary has at least read-only permissions for.
CVE-2017-0885 1 Nextcloud 1 Nextcloud Server 2022-10-04 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.
