CVE-2009-4353
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 Mobile Edition of TransWARE Active! mail 2003 build 2003.0139.0871 and earlier, and possibly other versions before 2003.0139.0911, does not remove the session ID in a Referer URL, which allows remote attackers to hijack web sessions via vectors such as an email with an embedded URL.
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 · moderate confidenceThe Mobile Edition of TransWARE Active! mail 2003 (build 2003.0139.0871 and earlier) leaks session IDs in Referer URLs when users click embedded links in emails. This allows remote attackers to hijack active web sessions by capturing the Referer header containing the valid session identifier.

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 TransWARE Active! mail installationLocate the TransWARE Active! mail software on the system - check for installation directories, services, or the web application filesAffected if The software is installed on the system
-
Determine the installed version and build numberCheck the application version information, typically found in the application itself, About dialog, or version metadata filesAffected if The version is Active! mail 2003 with build 2003.0139.0871 or earlier
-
Confirm Mobile Edition is in useVerify whether the Mobile Edition variant of Active! mail is deployed - this variant handles mobile/remote access and is the affected productAffected if The Mobile Edition of TransWARE Active! mail is in use
-
Test for session ID leakage in Referer headersLog into the web interface, click an embedded link within an email, and capture the HTTP request headers (using a proxy or browser dev tools) to observe if the session identifier appears in the Referer URLAffected if The session ID is visible in the Referer header when clicking email links
The environment is affected if TransWARE Active! mail Mobile Edition version 2003 build 2003.0139.0871 or earlier is installed and session IDs are exposed in Referer headers when users click embedded email links.

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 TransWARE Active! mail version 2003.0139.0911 or later, which addresses the session ID leakage. As a compensating control, implement session ID regeneration upon authentication and avoid passing session IDs in URLs.
