CVE-2024-29840
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 Web interface of Evolution Controller Versions 2.04.560.31.03.2024 and below contains poorly configured access control on DESKTOP_EDIT_USER_GET_PIN_FIELDS, allowing for an unauthenticated attacker to return the pin value of any user
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 Evolution Controller Web interface has a broken access control vulnerability in the DESKTOP_EDIT_USER_GET_PIN_FIELDS endpoint. An unauthenticated attacker can directly invoke this API to retrieve plaintext PIN values of any user in the system without any authentication or authorization.

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 if Evolution Controller Web interface is runningLocate the Evolution Controller service or web application in your environment and confirm it is accessible via HTTP/HTTPSAffected if The Evolution Controller Web interface is present and running
-
Determine the installed Evolution versionCheck the installed version of Cs Technologies Evolution through the web interface, system files, or software inventoryAffected if The version is 2.04.560 or lower
-
Verify unauthenticated access to the vulnerable endpointSend a direct HTTP request to the DESKTOP_EDIT_USER_GET_PIN_FIELDS API endpoint without providing any authentication credentialsAffected if The endpoint responds with HTTP 200 and returns data without requiring login
-
Confirm PIN disclosure vulnerabilityInspect the response from the DESKTOP_EDIT_USER_GET_PIN_FIELDS endpoint to see if it contains plaintext PIN values for user accountsAffected if The endpoint returns plaintext PIN values for any user without authentication
Your environment is affected if Cs Technologies Evolution version 2.04.560 or lower is running and the DESKTOP_EDIT_USER_GET_PIN_FIELDS endpoint is accessible without authentication and returns plaintext user PINs.

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 dataImplement proper authentication and role-based authorization checks on the DESKTOP_EDIT_USER_GET_PIN_FIELDS endpoint to ensure only authenticated administrators can access user PIN data. Consider removing PIN retrieval functionality from unauthenticated endpoints entirely or hashing PINs.
