OpenStack Swift

An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file as part of a GET URI. This allows attackers to bypass authentication by inserting a token into an X-Auth-Token header of a new request. NOTE: github.com/openstack/swauth URLs do not mean that Swauth is maintained by an official OpenStack project team.

OpenStack Object Storage (swift) before 1.7.0 uses the loads function in the pickle Python module unsafely when storing and loading metadata in memcached, which allows remote attackers to execute arbitrary code via a crafted pickle object.

OpenStack Object Storage (Swift) before 2.3.1 (Kilo), 2.4.x, and 2.5.x before 2.5.1 (Liberty) do not properly close server connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

OpenStack Object Storage (Swift) before 2.4.0 does not properly close client connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying 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 impacts both s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively developed).

The OpenStack Python client library for Swift (python-swiftclient) 1.0 through 1.9.0 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

OpenStack Object Storage (Swift) before 2.3.0, when allow_version is configured, allows remote authenticated users to delete the latest version of an object by leveraging listing access to the x-versions-location container.

In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers (X-Container-Host, X-Container-Device, X-Delete-At-Host, X-Delete-At-Device) from client requests before forwarding them to object-servers. An authenticated user with write access can inject these headers to redirect container update requests to an attacker-controlled server, enabling server-side request forgery. The SSRF requests expose internal cluster metadata including storage policy indexes, partition mappings, device names, and when at rest encryption is enabled, cipher text and initialization vectors for the container-level encryption key. The attacker can also cause "ghost listings" in arbitrary containers via the shard-range redirect mechanism.

OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a PUT tempurl and a DLO object manifest that references an object in another container.

Cross-site scripting (XSS) vulnerability in OpenStack Swift 1.11.0 through 1.13.1 allows remote attackers to inject arbitrary web script or HTML via the WWW-Authenticate header.

The TempURL middleware in OpenStack Object Storage (Swift) 1.4.6 through 1.8.0, 1.9.0 through 1.10.0, and 1.11.0 allows remote attackers to obtain secret URLs by leveraging an object name and a timing side-channel attack.

In OpenStack Swift through 2.10.1, 2.11.0 through 2.13.0, and 2.14.0, the proxy-server logs full tempurl paths, potentially leaking reusable tempurl signatures to anyone with read access to these logs. All Swift deployments using the tempurl middleware are affected.

OpenStack Object Storage (Swift) before 2.2.0 allows remote authenticated users to bypass the max_meta_count and other metadata constraints via multiple crafted requests which exceed the limit when combined.

OpenStack Swift before 1.9.1 in Folsom, Grizzly, and Havana allows authenticated users to cause a denial of service ("superfluous" tombstone consumption and Swift cluster slowdown) via a DELETE request with a timestamp that is older than expected.

The v1 API in OpenStack Glance Essex (2012.1), Folsom (2012.2), and Grizzly, when using the single-tenant Swift or S3 store, reports the location field, which allows remote authenticated users to obtain the operator's backend credentials via a request for a cached image.
