CVE-2015-4717 (CCN-108555)

Assigned:2015-06-24
Published:2015-06-24
Updated:2015-10-22
Summary: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.
