CVE-2007-4073
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 · uneditedWebbler CMS before 3.1.6 does not properly restrict use of "mail a friend" forms, which allows remote attackers to send arbitrary amounts of forged e-mail. NOTE: this could be leveraged for spam or phishing attacks.
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 confidenceWebbler CMS versions prior to 3.1.6 contain a vulnerability in the 'mail a friend' feature that lacks proper restrictions. The form does not implement adequate controls such as rate limiting, CAPTCHA, or authentication, allowing remote attackers to send unlimited forged emails for spam or phishing campaigns.

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.
-
Confirm Webbler CMS installationIdentify whether Tincan Webbler CMS is present in your environment by checking for CMS-related files, headers, or application signatures.Affected if Webbler CMS is installed and accessible on the network.
-
Determine installed versionLocate and inspect version information for the Webbler CMS installation, typically found in configuration files, admin panels, or source code headers.Affected if The installed version is 3.1.4 or any earlier version prior to 3.1.6.
-
Locate mail-a-friend featureAccess the mail-a-friend functionality in the CMS, usually found as a form on article pages, user recommendations, or a dedicated /mailfriend/ path.Affected if The mail-a-friend feature exists and is publicly accessible without authentication.
-
Verify absence of rate limitingAttempt to submit multiple rapid requests to the mail-a-friend form and observe whether the system blocks or throttles repeated submissions.Affected if No rate limiting is enforced and unlimited emails can be sent in quick succession.
-
Check for CAPTCHA or authenticationInspect the mail-a-friend form to determine whether CAPTCHA challenges, user login requirements, or other human verification controls are present.Affected if No CAPTCHA, login requirement, or verification mechanism is implemented on the form.
You are affected if Webbler CMS version 3.1.4 or earlier is installed and the mail-a-friend feature is accessible without any rate limiting, CAPTCHA, or authentication controls.

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 Webbler CMS to version 3.1.6 or later, which contains the fix. Alternatively, implement rate limiting, CAPTCHA verification, and user authentication on the mail-a-friend form to prevent abuse.
