CVE-2013-2296
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWalrus in Eucalyptus before 3.2.2 does not verify authorization for the GetBucketLoggingStatus, SetBucketLoggingStatus, and SetBucketVersioningStatus bucket operations, which allows remote authenticated users to bypass intended restrictions on (1) modifying the logging setting, (2) modifying the versioning setting, or (3) accessing activity logs via a request.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAuthorization bypass vulnerability in Walrus (S3-compatible storage) in Eucalyptus before 3.2.2 where GetBucketLoggingStatus, SetBucketLoggingStatus, and SetBucketVersioningStatus bucket operations do not verify authorization, allowing authenticated users to modify logging/versioning settings and access activity logs without proper permissions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Eucalyptus installation and versionRun 'eucalyptus --version' or check the installed packages (e.g., 'rpm -q eucalyptus' or 'dpkg -l eucalyptus') to determine the installed Eucalyptus version.Affected if The installed version is 3.2.1 or lower, or matches any of these: 1.0, 1.1, 1.2, 1.3, 1.4, 1.5.1, 1.5.2, 1.6, 1.6.2, 2.0, or 2.0.0.
-
Confirm Walrus (S3 storage) is enabledCheck if Walrus service is running and accessible. Look for Walrus-related processes or check the Eucalyptus cloud configuration for 'walrus' in the enabled services list.Affected if Walrus (S3-compatible storage) is enabled and operational in the Eucalyptus environment.
-
Verify the bucket operation authorization behaviorUsing an S3-compatible client (such as s3cmd or boto), attempt to invoke GetBucketLoggingStatus, SetBucketLoggingStatus, or SetBucketVersioningStatus on a bucket you do not own or have no permission to modify. Use an authenticated user account that lacks administrative privileges for that bucket.Affected if The operations execute successfully and return logging or versioning configuration data for buckets the user does not own, indicating authorization is not being enforced.
-
Compare installed version against CVE-affected rangeReview the CVE details: affected versions are Eucalyptus <= 3.2.1, and versions 1.0 through 2.0.0 as listed. If your installation matches any of these versions and Walrus is active, the environment is vulnerable.Affected if The installed Eucalyptus version is 3.2.1 or lower, or is one of the specific 1.x/2.x versions listed in the affected products.
A user is affected if they are running any Eucalyptus version 3.2.1 or lower (or versions 1.0-2.0.0) with Walrus enabled, and the bucket logging/versioning API calls execute without proper authorization checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Eucalyptus version 3.2.2 or later which implements proper authorization checks for these bucket operations.
