- ceph - distributed storage and file system
Details
It was discovered that the Ceph Object Gateway (RGW) SigV4 handler did not
reject requests carrying x-amz- headers that were absent from the signed
header set. An attacker holding a presigned URL could possibly use this issue to
attach arbitrary unsigned x-amz- headers that RGW would honor, allowing them to escalate
their privileges beyond what the URL's signer intended.
