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
An issue was discovered in MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual through 2.11.2. An unauthenticated attacker is able to access files (that should have been restricted) via forceful browsing.

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

The mbCONNECT24 and related products (mymbCONNECT24, myREX24, myREX24.virtual) through version 2.11.2 contain a path traversal or insecure direct object reference vulnerability. An unauthenticated remote attacker can bypass authentication restrictions and access sensitive files on the filesystem by manipulating file paths in HTTP requests (forceful browsing), potentially exposing configuration files, credentials, or other sensitive data.

MitigationUpdate to version 2.11.2 or later which contains the vendor patch. If immediate patching is not possible, implement network-level access controls to restrict unauthenticated access to the application's file endpoints.

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 installed version of the product
    Access the web interface and look for version information in the about page, footer, help section, or system info page. If CLI access is available, check application logs or version files for the product.
    Affected if The detected version is 2.11.2 or lower for mbCONNECT24, mymbCONNECT24, Myrex24, or Myrex24.virtual
  2. Verify network exposure of the web interface
    Review firewall rules, network ACLs, or reverse proxy configuration to determine if the application's HTTP/HTTPS ports are reachable from untrusted networks or the internet without authentication.
    Affected if The web interface is directly exposed to untrusted networks without authentication barriers
  3. Test for path traversal vulnerability in HTTP requests
    Using a web proxy or curl, send an authenticated or unauthenticated HTTP GET request attempting to access files outside the web root. Common test patterns include manipulating path parameters with ../../ sequences to reach system files.
    Affected if The application returns file contents from outside the intended web directory, indicating successful path traversal
  4. Check for sensitive file exposure via forceful browsing
    Attempt to access common sensitive endpoints or files such as configuration directories, credential stores, or backup files by directly manipulating URL paths in requests to the application.
    Affected if Sensitive configuration files, credentials, or application data are returned in the HTTP responses

A system is affected if it runs version 2.11.2 or lower of the listed products AND has its web interface accessible to unauthenticated attackers who can exploit the path traversal to read sensitive files.

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 data
Upgrade available Upgrade to a release after 2.11.2
Interim mitigation

Update to version 2.11.2 or later which contains the vendor patch. If immediate patching is not possible, implement network-level access controls to restrict unauthenticated access to the application's file endpoints.
