CVE-2012-2532
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 · uneditedMicrosoft FTP Service 7.0 and 7.5 for Internet Information Services (IIS) processes unspecified commands before TLS is enabled for a session, which allows remote attackers to obtain sensitive information by reading the replies to these commands, aka "FTP Command Injection Vulnerability."
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 confidenceMicrosoft FTP Service 7.0 and 7.5 for IIS processes certain commands in plaintext before TLS encryption is established for a session, allowing remote attackers to capture sensitive information from the unencrypted command replies.

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 Microsoft FTP Service installation and versionCheck the FTP service version via registry key HKLM\SOFTWARE\Microsoft\Ftp Service\Version or by viewing the properties of ftpsvc.dll in %systemroot%\system32\inetsrv. Alternatively, run 'appcmd list modules' or check IIS Manager under IIS role services.Affected if The installed version is exactly 7.0 or 7.5 and FTP service is present.
-
Verify FTP site is configured and runningOpen IIS Manager and check if any FTP sites exist under the Sites node, or run 'appcmd list sites' to list active FTP bindings. Also check Services console for Microsoft FTP Service status.Affected if An FTP site is published and the FTP service is running.
-
Inspect FTP SSL/TLS configurationIn IIS Manager, select the FTP site, open FTP SSL Settings, and check the SSL policy. Verify whether it is set to 'Allow SSL', 'Require SSL', or is unchecked. This can also be checked via appcmd: %windir%\system32\inetsrv\appcmd list config /section:ftpServer /xml and inspect the sslPolicy attribute.Affected if SSL policy is set to 'Allow SSL' or is not explicitly configured to require TLS for all connections.
-
Test for plaintext command processingConnect to the FTP server using a client (like Windows command-line ftp or FileZilla) without explicitly requesting TLS encryption (use non-TLS mode or connect to port 21 without AUTH TLS). Observe if server responses containing sensitive information are received in plaintext before any encryption negotiation occurs.Affected if Server responds with sensitive data in plaintext before TLS handshake completes when connecting without encryption.
A system is affected if it runs Microsoft FTP Service version 7.0 or 7.5, has an active FTP site, and does not enforce TLS/SSL for all FTP connections (SSL policy is not set to Require SSL).
Generated from the published advisory. Verify against your own configuration.
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 dataApply available Microsoft security updates for affected FTP Service versions, disable the FTP service if not required, or ensure FTP over explicit TLS is properly configured and enforced.
