CVE-2011-4762
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 · uneditedParallels Plesk Small Business Panel 10.2.0 sends incorrect Content-Type headers for certain resources, which might allow remote attackers to have an unspecified impact by leveraging an interpretation conflict involving smb/app/top-categories-data/ 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 confidenceParallels Plesk Small Business Panel 10.2.0 incorrectly sends Content-Type headers for certain resources (specifically smb/app/top-categories-data/ and related files), creating an interpretation conflict where the browser may process the response differently than intended. This MIME type confusion could allow remote attackers to execute unauthorized actions by causing the client to misinterpret the resource type.

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 Parallels Plesk Small Business Panel is installedIdentify if the Plesk Small Business Panel web application is running on the target system. Check for Plesk-related services, web directories, or the presence of Plesk administrative interfaces.Affected if The system has Parallels Plesk Small Business Panel installed and accessible via web browser or command line.
-
Verify the exact version numberAccess the Plesk administrative interface or check the installed package version. Typically found in the Plesk control panel footer, or via command line using 'plesk --version' or checking installed RPM/DEB packages.Affected if The installed version is exactly 10.2.0.
-
Identify if affected endpoints are accessibleAttempt to access the URLs 'smb/app/top-categories-data/' and related files within the Plesk web directory structure. These are typically found under the Plesk admin web root.Affected if The specific endpoints (smb/app/top-categories-data/ and related files) are accessible and respond to HTTP requests.
-
Inspect Content-Type headers on affected resourcesUse a web browser's developer tools, curl, or a similar HTTP client to request the affected URLs and examine the HTTP response headers. Specifically look at the Content-Type header in the response.Affected if The Content-Type header returned does not match the actual resource type (e.g., returns an incorrect MIME type that causes browser interpretation conflicts).
A system is affected if it runs Parallels Plesk Small Business Panel version 10.2.0 and serves the vulnerable endpoints with mismatched Content-Type headers.

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 dataConfigure the web server/application to send correct Content-Type headers for all served resources, or upgrade to a patched version of Plesk that resolves the MIME type misconfiguration.
