CVE-2006-4767
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 · uneditedMultiple directory traversal vulnerabilities in Stefan Ernst Newsscript (aka WM-News) 0.5beta allow remote attackers to (1) read arbitrary local files via a .. (dot dot) sequence in the ide parameter in modify.php and (2) write to arbitrary local files via a .. sequence in the var parameter in add_go.php. NOTE: the provenance of this information is unknown; the details are obtained from third party information.
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 confidenceWM-News 0.5beta contains two directory traversal vulnerabilities: modify.php allows reading arbitrary local files via `..` sequences in the ide parameter, while add_go.php allows writing arbitrary local files via `..` sequences in the var parameter.

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.
-
Locate WM-News installationSearch the web server document root for directories containing 'wm-news', 'news', or files named 'modify.php' and 'add_go.php'. Common paths include /news/, /wm-news/, or /cgi-bin/news/.Affected if The application directory exists on the server with the files modify.php and add_go.php present.
-
Confirm the installed versionCheck the source code, version file, or readme for the version string. Look for a version.php, readme.txt, or the main index.php for a version declaration. Also check the HTTP banner if the server emits one.Affected if The version is exactly 0.5_beta (or any variant like 0.5beta, 0.5 Beta).
-
Verify modify.php is accessibleAttempt an HTTP request to the modify.php script in the news directory, for example: GET /path/to/modify.php. Also check if the 'ide' parameter is accepted by submitting a test request with ide=test (without path traversal characters).Affected if modify.php exists and responds to requests, accepting the 'ide' parameter without requiring authentication.
-
Verify add_go.php is accessibleAttempt an HTTP request to the add_go.php script in the news directory, for example: GET /path/to/add_go.php. Also check if the 'var' parameter is accepted by submitting a test request with var=test (without path traversal characters).Affected if add_go.php exists and responds to requests, accepting the 'var' parameter without requiring authentication.
If WM-News (Stefan Ernst Newsscript) version 0.5_beta is installed and the scripts modify.php and add_go.php are accessible without authentication, the environment is vulnerable to directory traversal attacks via the 'ide' and 'var' parameters respectively.

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 a patched version of WM-News or implement strict input validation with allowlist filtering for path traversal characters (`..`, `/`, `\`) and apply filesystem-level access controls to restrict file operations to intended directories.
