CVE-2006-2428
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 · uneditedadd.asp in DUware DUbanner 3.1 allows remote attackers to execute arbitrary code by uploading files with arbitrary extensions, such as ASP files, probably due to client-side enforcement that can be bypassed. NOTE: some of these details are obtained from third party information, since the raw source is vague.
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 add.asp component in DUware DUbanner 3.1 contains an arbitrary file upload vulnerability. The application performs file type validation only on the client side (likely via JavaScript), which can be bypassed by directly manipulating HTTP requests. This allows remote attackers to upload malicious files such as ASP webshells and execute arbitrary code on the server.

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 if DUbanner 3.1 is installedSearch the web server for files or directories containing 'dubanner' or 'DUbanner' in the path. Check web application directories for presence of the DUbanner application.Affected if DUbanner 3.1 is found installed on the server
-
Locate the add.asp upload componentSearch for the file 'add.asp' within the DUbanner installation directory. Common paths may include /add.asp, /admin/add.asp, or /components/add.asp within the DUbanner web root.Affected if The add.asp file exists in the application directory
-
Verify the upload functionality is accessibleAttempt an HTTP request to the add.asp endpoint (e.g., GET request to the identified path) to confirm the file upload form is reachable without authentication.Affected if The add.asp upload form loads and accepts requests without requiring login
-
Check for suspicious uploaded filesReview the upload directory (typically /banner/ or /uploads/ within DUbanner) for file types that should not be present, especially .asp, .aspX, .cer, .asa, or other executable extensions.Affected if Unexpected .asp or other script files are found in upload directories
A server is affected if DUbanner version 3.1 is installed with the add.asp component accessible and server-side file validation is not enforced.

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 dataImplement server-side file validation (checking file content/magic bytes rather than just extensions) and disable or restrict the vulnerable upload functionality until properly secured. Review and remove any previously uploaded malicious files from the server.
