CVSS v3.1 |
| ownCloud Desktop before 2.2.3 allows local users to execute arbitrary code and possibly gain privileges via a Trojan library in a "special path" in the C: drive. |
| A logical error in ownCloud Server before 10.0.2 caused disclosure of valid share tokens for public calendars. Thus granting an attacker potentially access to publicly shared calendars without knowing the share token. |
| 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. |
| 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. |
| 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. |
| ownCloud Server before 8.2.12, 9.0.x before 9.0.10, 9.1.x before 9.1.6, and 10.0.x before 10.0.2 are vulnerable to XSS on error pages by injecting code in url parameters. |
| 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. |
| 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. |
| 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. |
| apps/calendar/ajax/events.php in ownCloud before 4.5.11 and 5.x before 5.0.6 does not properly check the ownership of a calendar, which allows remote authenticated users to download arbitrary calendars via the calendar_id parameter. |
| Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.15, 4.5.x before 4.5.11, and 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via the url parameter to (1) apps/bookmarks/ajax/addBookmark.php or (2) apps/bookmarks/ajax/editBookmark.php. |
| Open redirect vulnerability in the Login Page (index.php) in ownCloud before 5.0.6 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the redirect_url parameter. |
| Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.15, 4.5.x before 4.5.11, and 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors. |
| ownCloud Server before 5.0.19, 6.x before 6.0.7, and 7.x before 7.0.5 allows remote authenticated users to bypass the file blacklist and upload arbitrary files via a file path with UTF-8 encoding, as demonstrated by uploading a .htaccess file. |
| Multiple cross-site scripting (XSS) vulnerabilities in ownCloud 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via the (1) tag parameter to apps/bookmarks/ajax/addBookmark.php or (2) dir parameter to apps/files/ajax/newfile.php, which is passed to apps/files/js/files.js. |
| SQL injection vulnerability in lib/db.php in ownCloud Server 5.0.x before 5.0.6 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors. |
| The contacts application in ownCloud before 4.5.10 and 5.x before 5.0.5 does not properly check the ownership of contacts, which allows remote authenticated users to download arbitrary contacts via unspecified vectors. |
| Multiple cross-site scripting (XSS) vulnerabilities in the contacts application in ownCloud Server Community Edition before 5.0.19, 6.x before 6.0.7, and 7.x before 7.0.5 allow remote authenticated users to inject arbitrary web script or HTML via a crafted contact. |
| SQL injection vulnerability in lib/bookmarks.php in ownCloud Server 4.5.x before 4.5.11 and 5.x before 5.0.6 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors. |
| lib/base.php in ownCloud before 4.0.8 does not properly validate the user_id session variable, which allows remote authenticated users to read arbitrary files via vectors related to WebDAV. |
