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 COSPAS-SARSAT protocol allows remote attackers to forge messages, replay encrypted messages, conduct denial of service attacks, and send private messages (unrelated to distress alerts) via a crafted 406 MHz digital signal.

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 COSPAS-SARSAT international satellite-based search and rescue protocol contains a vulnerability that allows remote attackers to forge messages, replay encrypted messages, conduct denial of service attacks, and send unrelated private messages via crafted 406 MHz digital signals. This is a protocol-level flaw affecting the 406 MHz distress beacon frequency used by emergency beacons and satellites.

MitigationImplement cryptographic authentication and message validation at ground receiving stations to verify signal authenticity and prevent replay attacks; deploy anomaly detection systems to identify and filter malformed or unauthorized 406 MHz signals.

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 Cospas-Sarsat 406 MHz equipment in your environment
    Inventory all emergency beacons operating on 406 MHz (EPIRBs for maritime, ELTs for aviation, PLBs for personal) and ground receiving stations that process Cospas-Sarsat signals
    Affected if Any 406 MHz beacons or ground receiving stations are present in your infrastructure
  2. Check for cryptographic authentication implementation
    Inspect ground receiving station documentation and configuration to determine if message authentication using the Cospas-Sarsat authentication scheme is enabled and operational
    Affected if Cryptographic authentication is not implemented or is disabled on ground receiving stations
  3. Verify message validation and replay protection
    Review receiving station configuration and signal processing settings to confirm message validation and replay attack prevention mechanisms are active
    Affected if No message validation or replay protection is configured on receiving equipment
  4. Inspect for anomaly detection on 406 MHz signals
    Check whether monitoring systems are deployed to detect malformed, forged, or unauthorized 406 MHz distress signals
    Affected if No anomaly detection system is in place for 406 MHz signal monitoring
  5. Identify legacy beacon usage
    Survey deployed beacons for older models that lack cryptographic authentication capability per Cospas-Sarsat specifications
    Affected if Legacy beacons without authentication capability are in operation

If you operate Cospas-Sarsat 406 MHz equipment without cryptographic authentication, message validation, replay protection, and anomaly detection at ground receiving stations, your environment is affected by this protocol vulnerability.
