DrawIO for ownCloud is an application for using DrawIO with the file storage, synchronization, and sharing application ownCloud Classic. In DrawIO for ownCloud prior to version 1.0.2, which corresponds to ownCloud 10 prior to version 10.15.3, attackers with access to the DrawIO app can leverage improper neutralization of input during web page generation to achieve stored XSS. Upgrade ownCloud 10 to version 10.15.3 or later or upgrade DrawIO for ownCloud 10 to version 1.0.2 or later to receive a patch.

Anti-Virus for ownCloud is an anti-virus application for file storage, synchronization, and sharing application ownCloud. Versions of Anti-Virus for ownCloud before 1.2.3 are vulnerable to Server-Side Request Forgery (SSRF). This corresponds to versions of ownCloud 10 prior to 10.15.3. Upgrade ownCloud 10 to version 10.15.3 or later or upgrade Anti-Virus for ownCloud 10 to version 1.2.3 or later to receive a fix.

ownCloud is a file storage, synchronization, and sharing application. In ownCloud 10 prior to version 10.15.3, an attacker with administrative privileges can exploit a path traversal vulnerability in the system to execute arbitrary code. Upgrade ownCloud 10 to version 10.15.3 or later to receive a patch.

SharePoint for ownCloud is an application for using SharePoint with the file storage, synchronization, and sharing application ownCloud Classic. In SharePoint for ownCloud prior to version 0.4.1, which corresponds to ownCloud 10 prior to 10.15.3, an attacker with administrative privileges can use a SSRF vulnerability in the SharePoint app to execute arbitrary code on the system. Upgrade ownCloud 10 to version 10.15.3 or later to receive SharePoint for ownCloud 0.4.1, the fixed version.

ownCloud Core is the server-side component of the file storage, synchronization, and sharing application ownCloud Classic. In versions prior to 10.15.3, the Updater on ownCloud 10 before 10.15.3 has an exposed dangerous method or function. Attackers with administrative privileges may leverage functionality to execute arbitrary code. This issue has been fixed in version 10.15.3.

OwnCloud 8.1.8 contains a username enumeration vulnerability that allows remote attackers to discover user accounts by manipulating the share.php endpoint. Attackers can send crafted GET requests to /index.php/core/ajax/share.php with a wildcard search parameter to retrieve comprehensive user information.

ownCloud Guests before 0.12.5 allows unauthenticated user enumeration via the /apps/guests/register/{email}/{token} endpoint. Because of insufficient validation of the supplied token in showPasswordForm, the server responds differently when an e-mail address corresponds to a valid pending guest user rather than a non-existent user.

An issue in Owncloud android apk v.4.3.1 allows a physically proximate attacker to escalate privileges via the PassCodeViewModel class, specifically in the checkPassCodeIsValid method

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.

An issue was discovered in ownCloud owncloud/oauth2 before 0.6.1, when Allow Subdomains is enabled. An attacker is able to pass in a crafted redirect-url that bypasses validation, and consequently allows an attacker to redirect callbacks to a Top Level Domain controlled by the attacker.

An issue was discovered in ownCloud owncloud/graphapi 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The graphapi app relies on a third-party GetPhpInfo.php library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo). This information includes all the environment variables of the webserver. In containerized deployments, these environment variables may include sensitive data such as the ownCloud admin password, mail server credentials, and license key. Simply disabling the graphapi app does not eliminate the vulnerability. Additionally, phpinfo exposes various other potentially sensitive configuration details that could be exploited by an attacker to gather information about the system. Therefore, even if ownCloud is not running in a containerized environment, this vulnerability should still be a cause for concern. Note that Docker containers from before February 2023 are not vulnerable to the credential disclosure.

The Owncloud Android app uses content providers to manage its data. The provider FileContentProvider has SQL injection vulnerabilities that allow malicious applications or users in the same device to obtain internal information of the app.

The ownCloud Android app allows ownCloud users to access, share, and edit files and folders. Prior to version 3.0, the app has an incomplete fix for a path traversal issue and is vulnerable to two bypass methods. The bypasses may lead to information disclosure when uploading the app’s internal files, and to arbitrary file write when uploading plain text files (although limited by the .txt extension). Version 3.0 fixes the reported bypasses.

The ownCloud Android app allows ownCloud users to access, share, and edit files and folders. Version 2.21.1 of the ownCloud Android app is vulnerable to SQL injection in FileContentProvider.kt. This issue can lead to information disclosure. Two databases, filelist and ownclouddatabase, are affected. In version 3.0, the filelist database was deprecated. However, injections affecting ownclouddatabase remain relevant as of version 3.0.

The Docker image of ownCloud Server through 10.11 contains a misconfiguration that renders the trusteddomains config useless. This could be abused to spoof the URL in password-reset e-mail messages.

ownCloud owncloud/core before 10.10.0 Improperly Removes Sensitive Information Before Storage or Transfer.

ownCloud owncloud/android 2.20 has Incorrect Access Control for local attackers.

ownCloud owncloud/android before 2.20 has Incorrect Access Control for physically proximate attackers.

The filesantivirus component before 1.0.0 for ownCloud allows OS Command Injection via the administration settings.

The filesantivirus component before 1.0.0 for ownCloud mishandles the protection mechanism by which malicious files (that have been uploaded to a public share) are supposed to be deleted upon detection.

ownCloud owncloud/client before 2.9.2 allows Resource Injection by a server into the desktop client via a URL, leading to remote code execution.

Server Side Request Forgery (SSRF) vulnerability exists in owncloud/userldap < 0.15.4 in the settings of the userldap app. Administration role is necessary for exploitation.

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.

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.

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.

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.

ownCloud 10.7 has an incorrect access control vulnerability, leading to remote information disclosure. Due to a bug in the related API endpoint, the attacker can enumerate all users in a single request by entering three whitespaces. Secondary, the retrieval of all users on a large instance could cause higher than average load on the instance.

ownCloud owncloud/client before 2.7 allows DLL Injection. The desktop client loaded development plugins from certain directories when they were present.
