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
snomControl.swf in the central phone server for the Snom 320 SIP Phone allows remote attackers to cause a denial of service (application crash and corruption of call logs) via a "'); (double quote, quote, close parenthesis, semicolon) sequence in the "Call a number" field.

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 snomControl.swf Flash component in Snom 320 SIP Phone central server fails to properly validate input in the 'Call a number' field. The injection sequence "'); allows an attacker to break out of context and cause application crash and corruption of call logs through the embedded Flash application's improper handling of user-supplied data.

MitigationApply vendor patch for snomControl.swf if available; otherwise, restrict network access to the phone management interface or disable the Flash-based control component as a compensating control.

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 device is a Snom 320 SIP Phone
    Access the device web interface or check device identification via SIP NOTIFY or HTTP request to the phone's IP address. Look for 'snom 320' or 'Snom 320' in the server header or web page content.
    Affected if The device identifies itself as a Snom 320 SIP Phone
  2. Verify snomControl.swf is present
    Navigate to the phone's web interface and look for the snomControl.swf file, typically found at paths like /snomControl.swf or within the /flash/ directory of the web server.
    Affected if The snomControl.swf Flash file is accessible on the device's web server
  3. Confirm Flash-based control is enabled
    Access the phone's web interface and locate the 'Call a number' field or dial pad functionality that uses the snomControl.swf component. Check if the Flash interface loads and accepts input.
    Affected if The Flash-based control interface with the 'Call a number' field is accessible and functional
  4. Check web interface accessibility
    Attempt HTTP/HTTPS access to the phone's management interface IP address. Verify the administrative or user-facing web pages are reachable.
    Affected if The web interface is accessible from the network (local or remote)
  5. Identify if the vulnerable input field accepts special characters
    In the Flash component's 'Call a number' field, attempt to input the sequence "'); to observe if the application properly handles or rejects the injection.
    Affected if The application accepts the injection sequence without proper sanitization, potentially causing unexpected behavior

If the device is a Snom 320 with the snomControl.swf Flash component accessible and its 'Call a number' feature enabled, the environment is affected by this vulnerability.
