CVE-2003-0422
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 · uneditedApple QuickTime / Darwin Streaming Server before 4.1.3f allows remote attackers to cause a denial of service (crash) via a request to view_broadcast.cgi that does not contain the required parameters.
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 · high confidenceThe Darwin Streaming Server's view_broadcast.cgi script fails to validate required parameters before processing requests. When a remote attacker sends a request without the expected parameters, the CGI script crashes due to missing input validation, causing a denial of service condition.

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 Darwin Streaming Server is installedCheck for the presence of Darwin Streaming Server by looking for its installation directory (typically /usr/local/mtwilson or /Library/QuickTimeStreaming) or by querying installed packages if using a package managerAffected if Darwin Streaming Server is found on the system
-
Determine the installed versionLook for a version file or check the server binary version. Common locations: /usr/local/mtwilson/StreamingServerVersion, or run: /usr/local/mtwilson/bin/StreamingServer -version, or check the About dialog in admin interfaceAffected if Version is exactly 4.1.3 (vulnerable); versions 4.1.3f and later are fixed
-
Locate the view_broadcast.cgi scriptFind the CGI scripts directory - typically in the /cgi-bin/ folder under the web server root. Search for view_broadcast.cgi file: find / -name 'view_broadcast.cgi' 2>/dev/nullAffected if view_broadcast.cgi script exists in a web-accessible CGI directory
-
Verify the server is running and accessibleCheck if the streaming server process is running (ps aux | grep Streaming) and if the web interface or CGI is reachable on the configured port (default 8080 or 80)Affected if Server is running and network-accessible, making the vulnerable CGI script reachable
The environment is affected only if Darwin Streaming Server version 4.1.3 is installed, the view_broadcast.cgi script exists, and the server is running and accessible to remote attackers who can trigger the crash by sending requests without required parameters.

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 dataUpgrade to Darwin Streaming Server 4.1.3f or later, which includes proper parameter validation for the view_broadcast.cgi script. If immediate patching is not possible, consider restricting access to the CGI scripts via network-level filtering.
