25 CVE-2017-5865 200 +Info 2017-03-03 2017-03-08
4.3
None Remote Medium Not required Partial None None
The password reset functionality in ownCloud Server before 8.1.11, 8.2.x before 8.2.9, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 sends different error messages depending on whether the username is valid, which allows remote attackers to enumerate user names via a large number of password reset attempts.
26 CVE-2016-9468 284 2017-03-28 2019-10-09
5.0
None Remote Low Not required None Partial None
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.
27 CVE-2016-9467 284 2017-03-28 2019-10-09
5.0
None Remote Low Not required None Partial None
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.
28 CVE-2016-9466 79 XSS 2017-03-28 2019-10-09
4.3
None Remote Medium Not required None Partial None
Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Reflected XSS in the Gallery application. The gallery app was not properly sanitizing exception messages from the Nextcloud/ownCloud server. Due to an endpoint where an attacker could influence the error message, this led to a reflected Cross-Site-Scripting vulnerability.
29 CVE-2016-9465 79 XSS 2017-03-28 2019-10-09
3.5
None Remote Medium ??? None Partial None
Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Stored XSS in CardDAV image export. The CardDAV image export functionality as implemented in Nextcloud/ownCloud allows the download of images stored within a vCard. Due to not performing any kind of verification on the image content this is prone to a stored Cross-Site Scripting attack.
30 CVE-2016-9463 287 Bypass 2017-03-28 2019-10-09
6.8
None Remote Medium Not required Partial Partial Partial
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.
31 CVE-2016-9462 284 2017-03-28 2019-10-09
4.0
None Remote Low ??? None Partial None
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.
32 CVE-2016-9461 284 2017-03-28 2019-10-09
4.0
None Remote Low ??? None Partial None
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.
33 CVE-2016-9460 284 2017-03-28 2017-04-04
5.0
None Remote Low Not required None Partial None
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.
34 CVE-2016-9459 79 XSS 2017-03-28 2019-10-09
4.3
None Remote Medium Not required None Partial None
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.
35 CVE-2016-7419 79 XSS 2016-09-17 2017-04-07
3.5
None Remote Medium ??? None Partial None
Cross-site scripting (XSS) vulnerability in share.js in the gallery application in ownCloud Server before 9.0.4 and Nextcloud Server before 9.0.52 allows remote authenticated users to inject arbitrary web script or HTML via a crafted directory name.

ownCloud Server before 7.0.12, 8.0.x before 8.0.10, 8.1.x before 8.1.5, and 8.2.x before 8.2.2, when the "file_versions" application is enabled, does not properly check the return value of getOwner, which allows remote authenticated users to read the files with names starting with ".v" and belonging to a sharing user by leveraging an incoming share.
40 CVE-2016-1499 200 DoS +Info 2016-01-08 2018-10-09
7.5
None Remote Low ??? Partial None Complete
ownCloud Server before 8.0.10, 8.1.x before 8.1.5, and 8.2.x before 8.2.2 allow remote authenticated users to obtain sensitive information from a directory listing and possibly cause a denial of service (CPU consumption) via the force parameter to index.php/apps/files/ajax/scan.php.
41 CVE-2016-1498 79 XSS 2016-01-08 2016-01-12

icewind1991 SMB before 1.0.3 allows remote authenticated users to execute arbitrary SMB commands via shell metacharacters in the user argument in the (1) listShares function in Server.php or the (2) connect or (3) read function in Share.php.
44 CVE-2015-7298 2015-10-26 2021-06-16
5.1
None Remote High Not required Partial Partial Partial
ownCloud Desktop Client before 2.0.1, when compiled with a Qt release after 5.3.x, does not call QNetworkReply::ignoreSslErrors with the list of errors to be ignored, which makes it easier for remote attackers to conduct man-in-the-middle (MITM) attacks by leveraging a server using a self-signed certificate. NOTE: this vulnerability exists because of a partial CVE-2015-4456 regression.
45 CVE-2015-6670 2015-10-26 2017-11-04
4.0
None Remote Low ??? Partial None None
ownCloud Server before 7.0.8, 8.0.x before 8.0.6, and 8.1.x before 8.1.1 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to apps/calendar/export.php.

The virtual filesystem in ownCloud Server before 6.0.9, 7.0.x before 7.0.7, and 8.0.x before 8.0.5 does not consider that NULL is a valid getPath return value, which allows remote authenticated users to bypass intended access restrictions and gain access to users files via a sharing link to a file with a deleted parent folder.
