CVE-2011-3825
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 · uneditedZend Framework 1.11.3 in Zend Server CE 5.1.0 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 Validate.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 confidenceZend Framework 1.11.3 in Zend Server CE 5.1.0 contains improper error handling that allows remote attackers to directly request certain .php files (such as Validate.php), causing PHP to reveal the full server installation path in error messages. This information disclosure aids attackers in reconnaissance for 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.
-
Check Zend Framework versionLocate the version file in the Zend Framework installation directory, typically found in the 'Version.php' file within the library/Zend directory, or run 'zf show version' if the Zend Tool CLI is installedAffected if Version is exactly 1.11.3
-
Check Zend Server versionLook for the Zend Server version in the installed package, typically accessible via the Zend Server web interface under 'Server Setup' or by running 'zendctl.sh -v' from the command lineAffected if Version is exactly 5.1.0 (Zend Server CE)
-
Verify PHP display_errors is enabledCheck the PHP configuration file (php.ini) for the 'display_errors' directive, or create a PHP script containing 'phpinfo();' and access it to see the current runtime valueAffected if display_errors is set to On or On is present in the error reporting configuration
-
Test for path disclosure via direct PHP accessAttempt to directly access a framework PHP file such as Validate.php from the web root (e.g., http://yourhost/library/Zend/Validate.php or similar path depending on installation) and observe if the error message reveals the full server file system pathAffected if The error output displays the complete server file path (e.g., /usr/local/zend/...) rather than a generic message
You are affected only if you have exactly Zend Framework 1.11.3 or Zend Server CE 5.1.0 installed AND PHP display_errors is enabled, allowing direct web access to internal PHP files to expose server paths in error messages.

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 detailed PHP error messages in production environments, implement proper error handling that returns generic messages, and configure web server rules to prevent direct access to internal PHP files.
