CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
An issue was discovered in ownCloud owncloud/core before 10.13.1. An attacker can access, modify, or delete any file without authentication if the username of a victim is known, and the victim has no signing-key configured. This occurs because pre-signed URLs can be accepted even when no signing-key is configured for the owner of the files. The earliest affected version is 10.6.0. | 9.8 |
CRITICAL |
||
The Docker image of ownCloud Server through 10.11 contains a misconfiguration that renders the trusted_domains config useless. This could be abused to spoof the URL in password-reset e-mail messages. | 5.3 |
MEDIUM |
||
ownCloud owncloud/core before 10.10.0 Improperly Removes Sensitive Information Before Storage or Transfer. | 7.5 |
HIGH |
||
Session fixation on password protected public links in the ownCloud Server before 10.8.0 allows an attacker to bypass the password protection when they can force a target client to use a controlled cookie. | 5.4 |
MEDIUM |
||
A receiver of a federated share with access to the database with ownCloud version before 10.8 could update the permissions and therefore elevate their own permissions. | 9.8 |
CRITICAL |
||
The shareinfo controller in the ownCloud Server before 10.8.0 allows an attacker to bypass the permission checks for upload only shares and list metadata about the share. | 5.3 |
MEDIUM |
||
The public share controller in the ownCloud server before version 10.8.0 allows a remote attacker to see the internal path and the username of a public share by including invalid characters in the URL. | 5.3 |
MEDIUM |
||
ownCloud Server before 10.3.0 allows an attacker, who has received non-administrative access to a group share, to remove everyone else's access to that share. | 4.3 |
MEDIUM |
||
An issue was discovered in ownCloud before 10.4. Because of an SSRF issue (via the apps/files_sharing/external remote parameter), an authenticated attacker can interact with local services blindly (aka Blind SSRF) or conduct a Denial Of Service attack. | 8.3 |
HIGH |
||
An issue was discovered in ownCloud before 10.4. An attacker can bypass authentication on a password-protected image by displaying its preview. | 5.9 |
MEDIUM |
||
Deleting users with certain names caused system files to be deleted. Risk is higher for systems which allow users to register themselves and have the data directory in the web root. This affects ownCloud/core versions < 10.6. | 9.1 |
CRITICAL |
||
The CSRF (Cross Site Request Forgery) token check was improperly implemented on cookie authenticated requests against some ocs API endpoints. This affects ownCloud/core version < 10.6. | 4.3 |
MEDIUM |
||
ownCloud (Core) before 10.5 allows XSS in login page 'forgot password.' | 6.1 |
MEDIUM |
||
The fetch function in OAuth/Curl.php in Dropbox-PHP, as used in ownCloud Server before 6.0.8, 7.x before 7.0.6, and 8.x before 8.0.4 when an external Dropbox storage has been mounted, allows remote administrators of Dropbox.com to read arbitrary files via an @ (at sign) character in unspecified POST values. | 4.9 |
MEDIUM |
||
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. | 6.1 |
MEDIUM |
||
Inadequate escaping lead to XSS vulnerability in the search module in 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. To be exploitable a user has to write or paste malicious content into the search dialogue. | 5.4 |
MEDIUM |
||
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. | 5.3 |
MEDIUM |
||
An attacker is logged in as a normal user and can somehow make admin to delete shared folders in ownCloud Server before 10.0.2. | 6.5 |
MEDIUM |
||
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. | 6.1 |
MEDIUM |
||
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. | 5.3 |
MEDIUM |
||
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. | 4.3 |
MEDIUM |
||
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. | 4.3 |
MEDIUM |
||
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. | 3.7 |
LOW |
||
The autocomplete feature in the E-Mail share dialog 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 allows remote authenticated users to obtain sensitive information via unspecified vectors. | 4.3 |
MEDIUM |
||
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 allows remote authenticated users to cause a denial of service (server hang and logfile flooding) via a one bit BMP file. | 6.5 |
MEDIUM |
||
ownCloud server before 8.2.6 and 9.x before 9.0.3, when the gallery app is enabled, allows remote attackers to download arbitrary images via a direct request. | 5.9 |
MEDIUM |
||

MEDIUM |
||
Cross-site scripting (XSS) vulnerability in the OCS discovery provider component in 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 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors involving a URL. | 6.1 |
MEDIUM |
||
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. | 8.5 |
HIGH |
||
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. | 3.1 |
LOW |
||
ownCloud Server before 8.0.9 and 8.1.x before 8.1.4 allow remote authenticated users to obtain sensitive information via unspecified vectors, which reveals the installation path in the resulting exception messages. | 4.3 |
MEDIUM |
||

|||
The filename sanitization component in ownCloud Server before 6.0.8, 7.0.x before 7.0.6, and 8.0.x before 8.0.4 does not properly handle $_GET parameters cast by PHP to an array, which allows remote attackers to cause a denial of service (infinite loop and log file consumption) via crafted endpoint file names. | 7.8 |
|||
The external SMB storage driver in ownCloud Server before 6.0.8, 7.0.x before 7.0.6, and 8.0.x before 8.0.4 allows remote authenticated users to execute arbitrary SMB commands via a ; (semicolon) character in a file. | 9 |
|||
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. | 4 |
|||
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. | 9 |
|||
Cross-site scripting (XSS) vulnerability in the activity application in ownCloud Server before 7.0.5 and 8.0.x before 8.0.4 allows remote authenticated users to inject arbitrary web script or HTML via a " (double quote) character in a filename in a shared folder. | 3.5 |
|||
