CVE-2024-47866 Details
Description
Ceph is a distributed object, block, and file storage platform. In versions up to and including 19.2.3, using the argument `x-amz-copy-source` to put an object and specifying an empty string as its content leads to the RGW daemon crashing, resulting in a DoS attack. As of time of publication, no known patched versions exist.
A denial-of-service vulnerability has been identified in Ceph's RADOS Gateway (RGW) module, affecting versions through 19.2.3. The issue arises when the `x-amz-copy-source` header is used to copy an object while specifying an empty string as the content. This improper input validation causes the RGW daemon to crash, leading to a service disruption. Notably, this denial-of-service condition can be triggered even during unauthenticated S3 sessions, although AWS credentials are required to create the bucket and source object.
This vulnerability has been patched in Ceph version 8.1z4, which is set to be released this week.
