CVE-2025-34081
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 · uneditedThe 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 confidenceThe 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.

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 the Conprosys HMI System installationAccess 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
-
Determine the installed versionCheck 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 3.7.7Affected if The installed version is lower than 3.7.7
-
Check for phpinfo() accessibilityAttempt 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 authenticationAffected 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.
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 · scoped3.7.7
Upgrade to version 3.7.7 or later, or alternatively locate and disable/remove the phpinfo() debug page from the web server configuration.
Conprosys HMI System (CHS) version 3.7.7
- Backup the current Conprosys HMI System configuration and data before proceeding with any upgrade
- Download the fixed version 3.7.7 from the official Contec Co.,Ltd. source or authorized distributor
- Follow the vendor's documented upgrade procedure for CONPROSYS HMI System (CHS) to install version 3.7.7
- After upgrade, verify the system is functioning correctly
- Confirm that the phpinfo() debug page is no longer accessible to unauthenticated users by attempting to access common phpinfo() paths
