CVE-2011-3797
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 · uneditedProjectPier 0.8.0.3 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 public/upgrade/templates/layout.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 confidenceProjectPier 0.8.0.3 contains an information disclosure vulnerability where direct requests to certain PHP files (such as public/upgrade/templates/layout.php) trigger error messages that expose the full server installation path. This path disclosure can aid attackers in reconnaissance and further exploitation.

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 ProjectPier versionCheck the version file in the ProjectPier installation directory, typically found in a version.php, config.php, or README file within the root installation folderAffected if The installed version is exactly 0.8.0.3
-
Verify vulnerable file existsCheck if the file public/upgrade/templates/layout.php exists in the ProjectPier web root directoryAffected if The file public/upgrade/templates/layout.php is present in the installation
-
Test for path disclosure via direct requestSend an HTTP GET request directly to public/upgrade/templates/layout.php and observe if error messages or stack traces containing the full server filesystem path are returned in the responseAffected if The response contains absolute server paths (e.g., /var/www/html/ or C:\inetpub\...) that reveal the installation directory
-
Check PHP error display configurationReview the PHP configuration file (php.ini) or check the runtime configuration using phpinfo() for the display_errors settingAffected if display_errors is set to On (enabled), which allows error messages with path information to be displayed to users
You are affected if ProjectPier version 0.8.0.3 is installed, the vulnerable file exists, direct access to it reveals server paths, and PHP display_errors is enabled.
Generated from the published advisory. Verify against your own configuration.
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 verbose error messaging in PHP configuration (display_errors=Off) and implement custom error handlers that present generic error pages without exposing system paths.
