CVE-2011-3823
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 · uneditedYamamah 1.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by themes/default/index.php and certain other files.
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 confidenceYamamah 1.0 contains an information disclosure vulnerability where direct requests to certain PHP files (such as themes/default/index.php) reveal the full server installation path in error messages. This path disclosure can aid attackers in reconnaissance by revealing filesystem locations.

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 Yamamah 1.0 installationLocate the Yamamah installation directory on the web server. Check for the presence of typical Yamamah files such as index.php in the root, configuration files, or the themes/ directory structure.Affected if The application directory contains Yamamah version 1.0 files, particularly the themes/default/ directory structure.
-
Identify the vulnerable file pathCheck if the file themes/default/index.php exists within the Yamamah installation directory. This is the primary file mentioned as vulnerable to direct request path disclosure.Affected if The file themes/default/index.php exists and is accessible within the web root.
-
Test for path disclosure via direct requestSend an HTTP GET request directly to themes/default/index.php (or similar PHP files in the themes/ directory). Observe whether the response includes the full server filesystem path in any error messages, warnings, or stack traces.Affected if The response contains the full server filesystem path (for example, /var/www/html/yamamah/themes/default/index.php) in an error message or warning.
-
Check PHP error display configurationReview the PHP configuration (php.ini) or check the application code for the error_reporting and display_errors settings. These determine whether PHP errors are visible to remote attackers.Affected if PHP display_errors is enabled (set to On) or error reporting is set to show warnings/notices, allowing path information to be returned in HTTP responses.
A user is affected if Yamamah 1.0 is installed, the vulnerable PHP files in the themes/ directory exist and are directly accessible, and PHP error display is enabled, resulting in full filesystem path disclosure in error responses.

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 dataDisable PHP error display and implement proper error handling to prevent path disclosure. Additionally, restrict direct access to include files by adding access controls or moving them outside the webroot.
