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 the exos 9300 server, a SOAP API is reachable on port 8002. This API does not require any authentication prior to sending requests. Therefore, network access to the exos server allows e.g. the creation of arbitrary access log events as well as querying the 2FA PINs associated with the enrolled chip cards.

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 exos 9300 server exposes an unauthenticated SOAP API on port 8002. Anyone with network access can send requests without credentials, enabling creation of arbitrary access log entries and extraction of 2FA PINs associated with enrolled chip cards.

MitigationRestrict network access to port 8002 via firewall or ACLs to trusted sources only, or enable authentication on the SOAP API if supported by the vendor.

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. Verify port 8002 is open and listening
    Run 'netstat -an | grep 8002' or 'nmap -p 8002 <target>' to determine if port 8002 is exposed on the system
    Affected if Port 8002 is found to be listening or accessible from the network
  2. Identify the service on port 8002
    Connect to port 8002 using curl or telnet and examine the HTTP response headers and banner, or run 'nmap -sV -p 8002 <target>' to identify the service
    Affected if The service is identified as the Exos 9300 SOAP API or related HTTP service
  3. Test SOAP API authentication requirement
    Send a crafted SOAP request to port 8002 without any credentials (e.g., curl -X POST http://<target>:8002/) and observe if a valid response is returned without authentication headers
    Affected if The API returns a valid response without requiring any authentication token, session, or credentials
  4. Check for 2FA PIN retrieval capability
    Send a SOAP request attempting to query 2FA/PIN enrollment data to the endpoint and verify if sensitive authentication data is returned without authorization
    Affected if The API returns 2FA PINs or chip card enrollment information without proper authorization
  5. Verify audit log manipulation is possible
    Send a SOAP request to create an access log entry with arbitrary data and confirm the log is created without authentication
    Affected if The API allows creation of arbitrary access log events without credentials, compromising audit integrity

The environment is affected if an Exos 9300 server has port 8002 open with an unauthenticated SOAP API that allows access to 2FA PINs or log manipulation without credentials.
