CVE-2025-41737
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 · uneditedDue to webserver misconfiguration an unauthenticated remote attacker is able to read the source of php modules.
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 confidenceDue to webserver misconfiguration, an unauthenticated remote attacker can read the source code of PHP modules. This information disclosure could expose credentials, API keys, database connection strings, and business logic.

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 the firmware version of the Metz Connect Ewio2 deviceAccess the device administrative interface or check the system information page to identify the currently installed firmware versionAffected if The firmware version is below 2.2.0 (for example, 2.1.x or earlier)
-
Identify PHP source files on the web serverLocate PHP files on the device's web root directory by examining the web application structure or consulting device documentationAffected if PHP source files exist on the web server and are accessible via HTTP
-
Test whether PHP files are executed or served as plain textUse a web browser or HTTP client to request a known PHP file from the device (for example, http://<device-ip>/path/to/file.php)Affected if The HTTP response displays PHP source code as plain text instead of executing the script and returning its output
-
Check for directory listing exposureNavigate to common web directories on the device and observe if directory listings are displayedAffected if Directory listing is enabled and reveals file names including PHP source files
The device is affected if it runs firmware version below 2.2.0 AND PHP source files can be retrieved as plain text via HTTP requests rather than being executed server-side.
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.
dbcve · scoped2.2.0
Fix the webserver configuration to ensure PHP source files are executed rather than served as plain text, and disable directory listing. This typically involves verifying the PHP handler is properly configured and MIME types are correct.
2.2.0
- Obtain the firmware version 2.2.0 from the vendor (Ewio2) or authorized distribution channel
- Access the device administrative interface or use the vendor-provided firmware update mechanism
- Upload and install firmware version 2.2.0 or later
- Verify the installation was successful and the webserver configuration no longer allows PHP source code access
