CVE-2016-9461
This allowed an authenticated attacker with access to a read-only share to put new files in there.
MEDIUM 4.3EPSS 2.00%
Does this matter?
Lower severity and a low EPSS score (2.00%). Track it; it rarely justifies an emergency change on its own.
Description
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files.
