index.php before ownCloud 4.0.7 does not properly validate the oc_token cookie, which allows remote attackers to bypass authentication via a crafted oc_token cookie value.
It is recommended that all instances are upgraded to ownCloud Server 4.0.7.
The ownCloud team thanks the following people for their research and responsible disclosure of the above advisory:
CPE | Name | Operator | Version |
---|---|---|---|
owncloud server | lt | 4.0.7 |
