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.

Directory traversal vulnerability in the routing component in ownCloud Server before 7.0.6 and 8.0.x before 8.0.4, when running on Windows, allows remote attackers to reinstall the application or execute arbitrary code via unspecified vectors.

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.

The documents application in ownCloud Server 6.x before 6.0.6 and 7.x before 7.0.3 allows remote attackers to bypass the password-protection for shared files via the API.

Multiple unspecified vulnerabilities in the preview system in ownCloud 6.x before 6.0.6 and 7.x before 7.0.3 allow remote attackers to read arbitrary files via unknown vectors.

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.

The FTP backend in user_external in ownCloud Server before 5.0.18 and 6.x before 6.0.6 allows remote attackers to bypass intended authentication requirements via a crafted password.

The user_ldap (aka LDAP user and group backend) application in ownCloud before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 allows remote attackers to bypass authentication via a null byte in the password and a valid user name, which triggers an unauthenticated bind.

Cross-site scripting (XSS) vulnerability in the import functionality in the bookmarks application in ownCloud before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 allows remote authenticated users to inject arbitrary web script or HTML by importing a link with an unspecified protocol. NOTE: this can be leveraged by remote attackers using CVE-2014-9041.

The import functionality in the bookmarks application in ownCloud server before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 does not validate CSRF tokens, which allow remote attackers to conduct CSRF attacks.

The SFTP external storage driver (files_external) in ownCloud Server before 6.0.5 validates the RSA Host key after login, which allows remote attackers to obtain sensitive information by sniffing the network.

Incomplete blacklist vulnerability in ajax/upload.php in ownCloud before 5.0, when running on Windows, allows remote authenticated users to bypass intended access restrictions, upload files with arbitrary names, and execute arbitrary code via an Alternate Data Stream (ADS) syntax in the filename parameter, as demonstrated using .htaccess::$DATA to upload a PHP program.

Directory traversal vulnerability in the routing component in ownCloud Server before 5.0.17 and 6.0.x before 6.0.4 allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in a filename, related to index.php.

ownCloud Server before 4.5.7 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to /apps/calendar/export.php. NOTE: this issue has been reported as a cross-site request forgery (CSRF) vulnerability, but due to lack of details, it is uncertain what the root cause is.

Unspecified vulnerability in ownCloud Server before 4.0.12 allows remote attackers to obtain sensitive information via unspecified vectors related to "inclusion of the Amazon SDK testing suite." NOTE: due to lack of details, it is not clear whether the issue exists in ownCloud itself, or in Amazon SDK.

ownCloud Server before 6.0.1 does not properly check permissions, which allows remote authenticated users to access arbitrary preview pictures via unspecified vectors.

ownCloud Server before 5.0.16 and 6.0.x before 6.0.3 does not properly check permissions, which allows remote authenticated users to read the names of files of other users by leveraging access to multiple accounts.

The document application in ownCloud Server before 6.0.3 uses sequential values for the file_id, which allows remote authenticated users to enumerate shared files via unspecified vectors.

Multiple cross-site request forgery (CSRF) vulnerabilities in ownCloud Server before 6.0.3 allow remote attackers to hijack the authentication of users for requests that (1) conduct cross-site scripting (XSS) attacks, (2) modify files, or (3) rename files via unspecified vectors.

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.
