CVE-2011-3799
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 · uneditedReOS 2.0.5 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 padmin/blocks/vergal.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 confidenceReOS 2.0.5 contains PHP files that leak the full server filesystem path in error messages when accessed directly without proper application initialization, as demonstrated with padmin/blocks/vergal.php. This path disclosure aids attackers in reconnaissance for subsequent 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.
-
Confirm ReOS installationLocate ReOS web application files on the server, typically found in the web root directoryAffected if ReOS is installed and accessible via web
-
Verify ReOS version is 2.0.5Check version files or configuration within the ReOS installation directoryAffected if The installed version is exactly 2.0.5
-
Check for vulnerable PHP file existenceSearch for the file padmin/blocks/vergal.php within the ReOS installation directoryAffected if The file padmin/blocks/vergal.php exists in the ReOS directory
-
Test for path disclosure via direct file accessUse a web browser or curl to directly access the file padmin/blocks/vergal.php without proper application initialization (e.g., without loading the main application bootstrap)Affected if The response contains the full server filesystem path in an error message or stack trace
-
Verify PHP display_errors configurationCheck the PHP configuration file (php.ini) or use phpinfo() to determine if display_errors is set to OnAffected if display_errors is enabled (On) in the PHP configuration
You are affected if ReOS version 2.0.5 is installed, the vulnerable PHP files exist, and direct access to them reveals server filesystem paths in error messages.
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 PHP error display in production (display_errors=Off), add proper initialization checks to affected PHP files to prevent direct access, and implement error handling that returns generic messages instead of detailed stack traces.
