CVE-2022-47950
Description
A flaw was found in Swift's S3 XML parser. By supplying specially crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This issue impacts both s3api deployments (Rocky or later) and swift3 deployments (Queens and earlier, no longer actively developed). Only deployments with S3 compatibility enabled are affected.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
