CVE-2015-4717
CWE-399Published: October 21, 2015· Updated: Jun 17, 2026
7.8
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2015-4717 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
