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
Missing Authentication for Critical Function vulnerability in EMTA Grup PDKS allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects PDKS: from V3.04 before 20240603. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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 confidence

Missing authentication for critical function in EMTA Grup PDKS personnel/attendance management software allows unauthenticated remote attackers to access sensitive functionality due to incorrectly configured access control security levels. This critical vulnerability (CVSS 9.4) affects versions V3.04 before June 3, 2024, potentially exposing employee attendance records and system controls.

MitigationImplement proper authentication for all critical functions and restrict network exposure until a vendor patch is available; consider web application firewall controls as interim mitigation given no vendor response to disclosure.

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 EMTA Grup PDKS installation
    Scan network for the EMTA Grup PDKS web interface or check running web services for PDKS-related headers, paths, or application fingerprints
    Affected if EMTA Grup PDKS personnel/attendance management software is present in the environment
  2. Determine installed software version
    Access the application's login page, about section, or version information page, or check application files/configs for version metadata
    Affected if The version is V3.04 and was installed or last updated before June 3, 2024
  3. Verify web interface network exposure
    Determine if the PDKS web interface is accessible from untrusted networks or the public internet by reviewing firewall rules, reverse proxy configs, or network ACLs
    Affected if The web interface is directly exposed to untrusted networks without authentication gating
  4. Test unauthenticated access to critical functions
    Attempt to access sensitive endpoints such as attendance records, personnel data exports, or administrative functions without providing credentials
    Affected if Critical functions or sensitive data are accessible without any authentication
  5. Check access control configuration
    Review application configuration files, security settings, or API access controls for misconfigured privilege levels on sensitive functions
    Affected if Access control security levels are incorrectly configured to allow unauthenticated access to critical functions

If EMTA Grup PDKS V3.04 is present and the web interface is network-accessible with incorrectly configured access controls, the environment is affected by this unauthenticated access vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper authentication for all critical functions and restrict network exposure until a vendor patch is available; consider web application firewall controls as interim mitigation given no vendor response to disclosure.

Recommended fix Moderate confidence

EMTA Grup PDKS version 20240603 or later

  1. Identify current EMTA Grup PDKS version by checking the application interface or system configuration
  2. Download EMTA Grup PDKS version 20240603 or later from the vendor
  3. Backup the current PDKS database and configuration files
  4. Install the upgraded version (20240603 or newer) following standard upgrade procedures
  5. After upgrade, verify that authentication is now required for critical functions by attempting to access without credentials
  6. Confirm the access control security levels are properly configured and enforced
