Owncloud: Security Vulnerabilities
CVE-2023-49103
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.

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/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.

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 `owncloud_database`, are affected. In version 3.0, the `filelist` database was deprecated. However, injections affecting `owncloud_database` remain relevant as of version 3.0.

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 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.
