PRIOn knowledge basePRION:CVE-2016-9462Design/Logic Flaw
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions.
| CPE | Name | Operator | Version |
|---|---|---|---|
| nextcloud_server | lt | 9.0.52 | |
| owncloud | lt | 9.0.4 |
