CVE-2012-2724
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 · uneditedThe Simplenews module 6.x-1.x before 6.x-1.4, 6.x-2.x before 6.x-2.0-alpha4, and 7.x-1.x before 7.x-1.0-rc1 for Drupal reveals the email addresses of new mailing list subscribers when confirmation is required, which allows remote attackers to obtain sensitive information via the confirmation page.
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 confidenceThe Simplenews Drupal module before versions 6.x-1.4, 6.x-2.0-alpha4, and 7.x-1.0-rc1 exposes subscriber email addresses on the confirmation page when email confirmation is required. An unauthenticated remote attacker can access this page to harvest valid email addresses from the mailing list.

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 Simplenews module installationCheck the Drupal modules directory for the simplenews folder, or query the {system} database table: SELECT filename, version FROM {system} WHERE name = 'simplenews';Affected if The module is not found or returns NULL version (module not installed)
-
Determine installed Simplenews versionExamine the simplenews.info file in the module directory for the version line, or use the version from the database query aboveAffected if Version is 6.x-1.0 through 6.x-1.3, or 6.x-2.0 through 6.x-2.x, or exactly 7.x-1.0 (without -rc1 or later)
-
Verify email confirmation is enabledCheck Simplenews configuration at Administer > Site building > Modules > Simplenews (or admin/settings/simplenews), look for 'Require confirmation email' or 'Double opt-in' setting in the subscription settingsAffected if Email confirmation requirement is turned ON (this is the condition that makes the flaw exploitable)
-
Confirm subscription confirmation page exists and is accessibleTest access to the newsletter subscription confirmation URL (typically /newsletter/subscribe or /simplenews/subscribe with the confirmation token parameter) without authenticationAffected if The page loads and displays subscriber email addresses without requiring login
You are affected if Simplenews module versions 6.x-1.0 through 6.x-1.3, 6.x-2.0 through 6.x-2.x, or 7.x-1.0 are installed AND the email confirmation (double opt-in) feature is enabled, allowing unauthenticated access to the confirmation page displaying subscriber emails.

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 dataUpdate the Simplenews module to the patched versions (6.x-1.4, 6.x-2.0-alpha4, or 7.x-1.0-rc1 or later). Review subscription logs for signs of abuse during the vulnerable period.
