CVE-2007-4403
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 mIRC Control Plug-in for Winamp allows user-assisted remote attackers to execute arbitrary code via the '|' (pipe) shell metacharacter in the name of the song in a .mp3 file.
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 mIRC Control Plug-in for Winamp fails to sanitize the pipe character '|' from MP3 filenames before passing them to the system shell, allowing shell command injection when a user plays a maliciously named MP3 file.

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.
-
Verify Winamp is installedSearch for Winamp installation directories, typically under C:\Program Files\Winamp or C:\Program Files (x86)\Winamp, or check for Winamp in the list of installed programsAffected if Winamp is installed on the system
-
Locate the mIRC Control Plug-in fileBrowse to the Winamp\Plugins folder and search for any file with 'mirc' or 'mIRC' in the filename (typically a .dll file)Affected if A file named something like 'mirc.dll' or similar containing 'mirc' exists in the Winamp plugins directory
-
Confirm the plugin is enabledOpen Winamp, go to Options > Preferences > Plug-ins, and verify whether the mIRC Control Plug-in appears in the list and shows as enabled/loadedAffected if The mIRC Control Plug-in appears as enabled in Winamp's plug-in preferences
-
Check for suspicious MP3 filesExamine recently played or downloaded MP3 files in your music library for filenames containing pipe characters (|) or other shell metacharactersAffected if There are MP3 files with pipe characters or other special characters in their filenames that have been played using this Winamp installation
The user is affected if Winamp is installed with the mIRC Control Plug-in enabled, as all versions of this plugin contain the shell injection flaw when processing MP3 filenames with pipe characters.

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 dataUsers should avoid opening MP3 files from untrusted sources and consider removing the mIRC Control Plug-in for Winamp as it likely no longer receives security updates.
