Executive Summary

This vulnerability in Ceph versions up to and including 19.2.3 occurs when the argument `x-amz-copy-source` is used to put an object with an empty string as its content. This causes the RGW daemon to crash, leading to a denial of service (DoS) attack.

Impact Analysis

The vulnerability can cause the RGW daemon in Ceph to crash, resulting in a denial of service (DoS) condition. This means that the storage service could become unavailable, potentially disrupting access to stored data and impacting system availability.

Mitigation Strategies

Since no patched versions are available, immediate mitigation steps include monitoring and blocking requests that use the 'x-amz-copy-source' argument with empty string content to prevent triggering the RGW daemon crash. Additionally, consider restricting access to the RGW service to trusted clients only and implementing network-level protections such as firewalls or rate limiting to reduce exposure to potential DoS attacks.
