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.

Cross-site scripting (XSS) vulnerability in ownCloud 4.5.5, 4.0.10, and earlier allows remote attackers to inject arbitrary web script or HTML via the action parameter to core/ajax/sharing.php.

ownCloud Server 10.x before 10.3.1 allows an attacker, who has one outgoing share from a victim, to access any version of any file by sending a request for a predictable ID number.

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.

Zend Framework, 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.

Cross-site request forgery (CSRF) vulnerability in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2 allows remote attackers to hijack the authentication of users for requests that reset passwords via a crafted HTTP Host header.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud 4.5.5, 4.0.10, and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) unspecified parameters to apps/calendar/ajax/event/new.php or (2) url parameter to apps/bookmarks/ajax/addBookmark.php.

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

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

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 `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 application before 2.15 for Android allows attackers to use adb to include a PIN preferences value in a backup archive, and consequently bypass the PIN lock feature by restoring from this archive.

In the ownCloud application before 2.15 for Android, the lock protection mechanism can be bypassed by moving the system date/time into the past.

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.
