ownCloud is prone to a URI open-redirection vulnerability, multiple cross-site scripting vulnerabilities and multiple HTML- injection vulnerabilities because it fails to properly sanitize user-supplied input. An attacker could leverage the cross-site scripting issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie- based authentication credentials and launch other attacks. Attacker-supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie- based authentication credentials or control how the site is rendered to the user. Other attacks are also possible. Successful exploits may redirect a user to a potentially malicious site this may aid in phishing attacks. ownCloud 3.0.0 is vulnerable other versions may also be affected.

Updates are available. Please see the reference for more details.
