CVE-2005-3517
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 · uneditedChipmunk Scripts Guestbook allows remote attackers to obtain the installation path of the script via a URL that causes an error message to be displayed, such as a URL that contains a single quote (') in the start parameter of index.php.
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 confidenceChipmunk Scripts Guestbook contains an information disclosure vulnerability where the application fails to properly sanitize input to the 'start' parameter in index.php. When a single quote (') is submitted, the script triggers an error message that reveals the full installation path of the application, which can aid attackers in further reconnaissance.

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 Chipmunk Guestbook installationLocate index.php file in the web root directory that belongs to Chipmunk Scripts Guestbook. Check common paths such as /guestbook/, /gb/, or directly in the web root.Affected if The file index.php from Chipmunk Guestbook exists on the server
-
Locate the application installation pathReview your web server configuration or file system to determine the full directory path where the guestbook files are installed.Affected if Chipmunk Guestbook is installed in a known directory path on the server
-
Test the start parameter for path disclosureSend an HTTP request to the guestbook index.php with a single quote (') appended to the 'start' parameter, for example: GET /path/to/index.php?start='Affected if The response returns an error message that displays the full server filesystem path to the application
-
Verify error message contentExamine the HTTP response body for the error triggered by the single quote in the 'start' parameter. Look for path information such as /home/, /var/www/, or similar filesystem references.Affected if The error message contains absolute directory paths that reveal the server's folder structure
If Chipmunk Guestbook is installed and submitting a single quote to the 'start' parameter produces an error message exposing the filesystem installation path, the environment is affected by CVE-2005-3517.

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 dataImplement proper input validation and sanitization on all user-supplied parameters, particularly the 'start' parameter. Configure the application to display generic error messages rather than detailed stack traces that expose system paths.
