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 web framework in Cisco Transport Gateway for Smart Call Home (aka TG-SCH or Transport Gateway Installation Software) does not validate an unspecified parameter, which allows remote authenticated users to cause a denial of service (service crash) via a crafted string, aka Bug ID CSCuq31819.

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

Cisco Transport Gateway for Smart Call Home web framework fails to validate an unspecified parameter, allowing remote authenticated users to send a crafted string that causes the service to crash, resulting in denial of service.

MitigationApply the vendor patch from Cisco when available. Until then, restrict access to the web interface to only trusted authenticated users and monitor for service disruptions.

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. Confirm Cisco Transport Gateway is installed
    Identify whether the Cisco Transport Gateway for Smart Call Home software is installed on the system
    Affected if The product is not present in the environment
  2. Verify installed version is 4.0
    Check the installed version of Cisco Transport Gateway software - the vulnerability affects only version 4.0 exactly
    Affected if Version is exactly 4.0 (not earlier or later versions)
  3. Check if web framework is enabled
    Determine whether the web framework (web interface) is enabled on the Transport Gateway device
    Affected if Web framework is enabled and accessible to users
  4. Check remote access to web interface
    Verify if the web interface is accessible to remote authenticated users beyond trusted internal networks
    Affected if Remote authenticated users can access the web interface

Environment is affected only if Cisco Transport Gateway version 4.0 is installed with the web framework enabled and accessible to remote authenticated users.
