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
On iOS and Android devices, the ShoreTel Mobility Client app version 9.1.3.109 fails to properly validate SSL certificates provided by HTTPS connections, which means that an attacker in the position to perform MITM attacks may be able to obtain sensitive account information such as login credentials.

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 ShoreTel Mobility Client app version 9.1.3.109 for iOS and Android fails to properly validate SSL certificates during HTTPS connections, allowing an attacker performing a man-in-the-middle (MITM) attack to intercept sensitive authentication credentials transmitted by the app.

MitigationUpdate to a patched version of the ShoreTel Mobility Client that implements proper SSL certificate chain and hostname validation. Until patched, users should avoid using the app on untrusted networks.

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 ShoreTel Mobility Client on iOS devices
    Check iOS devices by going to Settings > General > iPhone Storage (or iPad Storage), or use MDM/EMM software to enumerate installed apps. Look for an app named ShoreTel Mobility Client or Mitel ShoreTel Mobility Client.
    Affected if The app is present on any iOS device in the environment
  2. Identify ShoreTel Mobility Client on Android devices
    Check Android devices by navigating to Settings > Apps > Apps, or use MDM/EMM software to enumerate installed applications. Look for an app named ShoreTel Mobility Client or Mitel ShoreTel Mobility Client.
    Affected if The app is present on any Android device in the environment
  3. Determine the installed version number
    For iOS: In Settings > General > iPhone Storage, tap on ShoreTel Mobility Client to view the Version number. For Android: In Settings > Apps > [App Name], tap on App info to view the Version. Alternatively, query via MDM/EMM console or mobile device management reports.
    Affected if The version displayed is exactly 9.1.3.109
  4. Verify the vulnerability applies
    The vulnerability exists in version 9.1.3.109 due to improper SSL certificate chain and hostname validation. This specific version does not validate SSL certificates properly when transmitting authentication credentials over HTTPS.
    Affected if The installed version is exactly 9.1.3.109 and the app is used to transmit authentication credentials over HTTPS networks

If the ShoreTel Mobility Client version 9.1.3.109 is installed on any iOS or Android device in the environment, the improper SSL certificate validation vulnerability is present and sensitive authentication credentials could be intercepted via MITM attacks.
