CVE-2016-9579
A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket. A remote unauthenticated attacker could use this flaw to cause denial of service by sending a specially-crafted cross-origin HTTP request. Ceph branches 1.3.x and 2.x are affected.
