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 · unedited
SmarterTools SmarterStats 6.2.4100 sends incorrect Content-Type headers for certain resources, which might allow remote attackers to have an unspecified impact by leveraging an interpretation conflict involving frmCustomReport.aspx and certain other files. NOTE: it is possible that only clients, not the SmarterStats product, could be affected by this issue.

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 confidence

SmarterTools SmarterStats 6.2.4100 sends incorrect Content-Type headers for certain resources including frmCustomReport.aspx and other files. This MIME type mismatch creates an interpretation conflict between client and server, potentially allowing MIME sniffing attacks where the client may incorrectly interpret file content based on actual content rather than declared Content-Type.

MitigationRestrict access to affected endpoints until a vendor patch is available; if possible, configure the web server to enforce strict Content-Type headers or disable MIME type sniffing via X-Content-Type-Options headers.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm SmarterStats installation and version
    Locate the SmarterStats installation directory and check the version information, typically found in the application executable or version file, or access the web interface and look for version display in the admin/about section
    Affected if The installed version is exactly 6.2.4100
  2. Identify the web server port and endpoint
    Check the SmarterStats service configuration to determine which port the web interface is running on (default is 9784 for the admin panel)
    Affected if The web interface is accessible on any port
  3. Verify frmCustomReport.aspx is accessible
    Request the file frmCustomReport.aspx through the web browser or curl command: curl -I http://<server>:<port>/frmCustomReport.aspx
    Affected if The file returns a response with an incorrect or missing Content-Type header, or the Content-Type does not match the expected value for an ASPX file (should be text/html)
  4. Test for MIME sniffing vulnerability
    Send a request to an affected file and examine the Content-Type header, then attempt to access the file directly to see if the browser might interpret it differently based on actual content rather than the declared type
    Affected if The server returns a Content-Type that does not match the actual file type, or returns no Content-Type header at all, allowing client-side MIME interpretation

The environment is affected if SmarterStats version 6.2.4100 is installed and the web server serves files like frmCustomReport.aspx with incorrect or missing Content-Type headers, allowing MIME sniffing attacks.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict access to affected endpoints until a vendor patch is available; if possible, configure the web server to enforce strict Content-Type headers or disable MIME type sniffing via X-Content-Type-Options headers.
