Descriptions

The RGW code in Ceph before 10.0.1, when authenticated-read ACL is applied to a bucket, allows remote attackers to list the bucket contents via a URL.

El código RGW en Ceph en versiones anteriores a 10.0.1, cuando la lectura autenticada ACL es aplicada a un compartimento, permite a atacantes remotos listar el contenido del compartimento a través de una URL.

A flaw was found in Ceph RGW code which allows an anonymous user to list contents of RGW bucket by bypassing ACL which should only allow authenticated users to list contents of bucket.

It was discovered that Ceph incorrectly handled the handle_command function. A remote authenticated user could use this issue to cause Ceph to crash, resulting in a denial of service. Rahul Aggarwal discovered that Ceph incorrectly handled the authenticated-read ACL. A remote attacker could possibly use this issue to list bucket contents via a URL. Diluga Salome discovered that Ceph incorrectly handled certain POST objects with null conditions. A remote attacker could possibly use this issue to cuase Ceph to crash, resulting in a denial of service. Various other issues were also addressed.
