A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.

CVE-2020-1700 ceph: connection leak in the RGW Beast front-end permits a DoS against the RGW server
An unexpected disconnect during processing of some ops with Beast front-end configured (the default in rhcs-4.0) can lead to permanent leak of a socket connection by radosgw.
Discussion:
Mitigation:
If Beast front end is in use, switch to CivetWeb to mitigate the issue. The following is an example of the /etc/ceph/ceph.conf file:
...
[client.rgw.node1]
rgw frontends = civetweb
