| Package | Affected versions | Patched versions |
|---|---|---|
| owncloud | ≤ 6.0.7 | |
| owncloud server | = 7.0.0= 7.0.1= 7.0.2= 7.0.3= 7.0.4= 7.0.5= 8.0.0= 8.0.2= 8.0.3 |
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.
