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 "Pioneer Bank & Trust Mobile Banking" by PIONEER BANK AND TRUST app 3.0.0 -- aka pioneer-bank-trust-mobile-banking/id603182861 for iOS does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

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 Pioneer Bank & Trust Mobile Banking iOS app version 3.0.0 fails to validate X.509 certificates from SSL servers, meaning it does not verify the server's certificate is trusted, valid, and matches the expected domain. This allows man-in-the-middle attackers to intercept traffic by presenting a forged certificate, exposing sensitive banking credentials and session data.

MitigationImplement proper SSL certificate validation in the iOS app using URLSession's default certificate handling or certificate pinning to verify the server's certificate chain, validity, and hostname before establishing secure connections.

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 app name and publisher
    On the iOS device, go to Settings > General > iPhone Storage (or Apps), locate the Pioneer Bank & Trust Mobile Banking app, and confirm the app name shows as 'Pioneer Bank & Trust Mobile Banking' by 'Meafinancial'
    Affected if The app name and publisher do not match 'Pioneer Bank & Trust Mobile Banking' by 'Meafinancial' - if they differ, this CVE does not apply
  2. Check the installed app version number
    In iPhone Storage/Apps settings, find the Pioneer Bank & Trust Mobile Banking app and record the version number displayed next to the app name
    Affected if The version number is exactly 3.0.0 - only this specific version is affected by this CVE
  3. Verify the app makes network connections
    Use a network proxy tool (such as Burp Suite or mitmproxy) to intercept traffic from the app to observe if SSL/TLS connections are established without proper certificate validation warnings
    Affected if The app establishes SSL/TLS connections to banking servers - the vulnerability manifests when the app accepts invalid or mismatched certificates without warning
  4. Confirm no certificate pinning is implemented
    Analyze the app's network traffic using the proxy tool - if invalid certificates are accepted without any validation errors or warnings, certificate validation is not occurring
    Affected if The app accepts forged or invalid SSL certificates without rejecting the connection - this indicates the certificate validation vulnerability is present

A defender is affected only if the Pioneer Bank & Trust Mobile Banking app by Meafinancial is installed at version 3.0.0 on iOS and makes network connections without proper SSL certificate validation.
