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 · unedited
The Contec Co.,Ltd. CONPROSYS HMI System (CHS) exposes a PHP phpinfo() debug page to unauthenticated users that may contain sensitive data useful for an attacker.This issue affects CONPROSYS HMI System (CHS): before 3.7.7.

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 confidence

The CONPROSYS HMI System exposes a phpinfo() debug page to unauthenticated users. The phpinfo() function outputs detailed PHP configuration including version numbers, loaded extensions, paths, environment variables, and server internals—information that significantly aids attackers in reconnaissance and planning further exploitation.

MitigationUpgrade to version 3.7.7 or later, or alternatively locate and disable/remove the phpinfo() debug page from the web server configuration.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Conprosys HMI System installation
    Access the web interface of the target system and look for indicators that it is the Conprosys HMI product (such as login page branding, title, or specific paths like /login.php or /index.php)
    Affected if The web application is confirmed to be Conprosys HMI System
  2. Determine the installed version
    Check the Conprosys HMI version information, typically found in an About page, system information page, or footer of the web interface. Compare the version number to 3.7.7
    Affected if The installed version is lower than 3.7.7
  3. Check for phpinfo() accessibility
    Attempt to access common phpinfo() endpoints such as /phpinfo.php, /info.php, or /phpinfo (if known paths exist) or use web fingerprinting to identify if a phpinfo() page is present and reachable without authentication
    Affected if The phpinfo() page is accessible to unauthenticated users, returning PHP configuration details including version, extensions, and paths

A user is affected if they are running Conprosys HMI System version lower than 3.7.7 and the phpinfo() debug page is accessible without authentication on their installation.
