"Multiple vulnerabilities were discovered in ownCloud, a cloud storage
web service for files, music, contacts, calendars and many more.

  - CVE-2015-3011
    Hugh Davenport discovered that the 'contacts'
    application shipped with ownCloud is vulnerable to
    multiple stored cross-site scripting attacks. This
    vulnerability is effectively exploitable in any browser.

  - CVE-2015-3012
    Roy Jansen discovered that the 'documents' application
    shipped with ownCloud is vulnerable to multiple stored
    cross-site scripting attacks. This vulnerability is not
    exploitable in browsers that support the current CSP
    standard.

  - CVE-2015-3013
    Lukas Reschke discovered a blacklist bypass
    vulnerability, allowing authenticated remote attackers
    to bypass the file blacklist and upload files such as
    the .htaccess files. An attacker could leverage this
    bypass by uploading a .htaccess and execute arbitrary
    PHP code if the /data/ directory is stored inside the
    web root and a web server that interprets .htaccess
    files is used. On default Debian installations the data
    directory is outside of the web root and thus this
    vulnerability is not exploitable by default."
