CVE-2003-0051
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 · uneditedparse_xml.cgi in Apple Darwin Streaming Administration Server 4.1.2 and QuickTime Streaming Server 4.1.1 allows remote attackers to obtain the physical path of the server's installation path via a NULL file parameter.
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 parse_xml.cgi script in Apple Darwin Streaming Administration Server 4.1.2 and QuickTime Streaming Server 4.1.1 is vulnerable to information disclosure. By supplying a NULL file parameter to parse_xml.cgi, remote attackers can obtain the physical path of the server's installation directory, potentially aiding further attacks.

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.
-
Identify installed streaming server versionCheck the version of Apple Darwin Streaming Server or QuickTime Streaming Server installed on the system. On Unix/Linux systems, this may be listed in installation logs, package managers, or server documentation. Compare your installed version to the affected ranges: Darwin Streaming Server = 4.1.2, QuickTime Streaming Server = 4.1.1.Affected if The installed version matches exactly 4.1.2 for Darwin Streaming Server or 4.1.1 for QuickTime Streaming Server.
-
Locate parse_xml.cgi scriptSearch for the parse_xml.cgi script in the web server's CGI directories, typically under the streaming server's admin web interface path (such as /cgi-bin/ or /admin/cgi-bin/). The exact path varies by installation.Affected if The parse_xml.cgi script exists on the server and is accessible via the web.
-
Verify CGI script is web-accessibleAttempt to access parse_xml.cgi through the web server using a browser or curl command. The typical URL pattern is http://server:port/cgi-bin/parse_xml.cgi or similar admin paths.Affected if The script responds to HTTP requests without authentication or returns a valid response.
-
Test for information disclosure vulnerabilitySend a request to parse_xml.cgi with an empty or NULL file parameter, such as: http://server/cgi-bin/parse_xml.cgi?file= or http://server/cgi-bin/parse_xml.cgi?file=%00Affected if The response reveals the physical file system path of the streaming server installation directory.
A server is affected if it runs Darwin Streaming Server 4.1.2 or QuickTime Streaming Server 4.1.1, has parse_xml.cgi accessible via web, and responds to a NULL file parameter request with disclosure of the server's physical installation path.

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 vendor patches from Apple for this vulnerability, or upgrade to a patched version of the streaming server. If patches are unavailable, disable or remove the parse_xml.cgi script and restrict administrative interface access.
