CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| Cross-site scripting (XSS) vulnerability in the Documents component in ownCloud Server 6.0.x before 6.0.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly related to the print_unescaped function. |
| settings/personal.php in ownCloud 4.5.x before 4.5.6 allows remote authenticated users to execute arbitrary PHP code via crafted mount point settings. |
| ownCloud Server before 6.0.3 does not properly check permissions, which allows remote authenticated users to (1) access the contacts of other users via the address book or (2) rename files via unspecified vectors. |
| Directory traversal vulnerability in lib/files/view.php in ownCloud before 4.0.15, 4.5.x 4.5.11, and 5.x before 5.0.6 allows remote authenticated users to access arbitrary files via unspecified vectors. |
| 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. |
| 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. |
| SabreDAV before 1.7.11, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack. |
| ownCloud Server before 5.0.16 and 6.0.x before 6.0.3 does not check permissions to the files_external application, which allows remote authenticated users to add external storage 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. |
| The default Flash Cross Domain policies in ownCloud before 5.0.15 and 6.x before 6.0.2 allows remote attackers to access user files via unspecified vectors. |
| Multiple cross-site scripting (XSS) vulnerabilities in ownCloud 4.5.x before 4.5.7 allow remote attackers to inject arbitrary web script or HTML via (1) a crafted iCalendar file to the calendar application, the (2) dir or (3) file parameter to apps/files_pdfviewer/viewer.php, or the (4) mountpoint parameter to /apps/files_external/addMountPoint.php. |
| Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.12 and 4.5.x before 4.5.7 allow remote authenticated administrators to inject arbitrary web script or HTML via the (1) site_name or (2) site_url parameter to apps/external/ajax/setsites.php. |
| SQL injection vulnerability in addressbookprovider.php in ownCloud Server before 5.0.1 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors, related to the contacts application. |
| Session fixation vulnerability in ownCloud before 6.0.2, when PHP is configured to accept session parameters through a GET request, allows remote attackers to hijack web sessions via unspecified vectors. |
| Cross-site request forgery (CSRF) vulnerability in apps/calendar/ajax/settings/settimezone in ownCloud before 4.0.12 allows remote attackers to hijack the authentication of users for requests that change the timezone via the timezone parameter. |
| The OC_Util::getUrlContent function in ownCloud Server before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 allows remote attackers to read arbitrary files via a file:// protocol. |
| Multiple cross-site scripting (XSS) vulnerabilities in js/viewer.js in ownCloud before 4.5.12 and 5.x before 5.0.7 allow remote attackers to inject arbitrary web script or HTML via vectors related to shared files. |
