Cross-site scripting via GetObject header splitting
Published Apr 23, 2020 · Updated Aug 4, 2024
Cross-site scripting in the Object Gateway in Ceph allows remote attackers to execute script through an anonymous S3 GetObject request. RGWGetObj_ObjStore_S3::send_response_data copies response-* query values into HTTP response headers without rejecting control characters, permitting CRLF header injection. Exploitation requires a victim to request a known, publicly readable object large enough to carry the attack body; the resulting script runs in that victim's browser.
