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 Nano Digest (aka com.magzter.nanodigest) application 3.0 for Android 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 Nano Digest Android application version 3.0 fails to validate X.509 certificates from SSL servers, accepting any certificate presented during SSL/TLS connections. This allows man-in-the-middle attackers to intercept encrypted communications by presenting crafted certificates, enabling server spoofing and theft of sensitive data.

MitigationUpdate the application to implement proper SSL certificate validation, including hostname verification and chain-of-trust validation against a trusted Certificate Authority store, or implement certificate pinning for known trusted 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 if Nano Digest app is installed
    Check the installed applications on the Android device for 'Nano Digest' or 'Magzter Nano Digest'
    Affected if The application is present on the device
  2. Verify the installed version
    Check the version number of the Nano Digest application - look for version 3.0 specifically
    Affected if The installed version is exactly 3.0 (the only affected version listed)
  3. Confirm SSL certificate validation is not enforced
    Attempt to proxy SSL/TLS traffic through a test certificate authority and observe if the app accepts the untrusted certificate during connections
    Affected if The app successfully connects when presented with an invalid or self-signed certificate, indicating certificate validation is not performed

The environment is affected if Nano Digest version 3.0 is installed and the app accepts invalid SSL certificates during connections.
