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
Cisco TelePresence IX5000 8.0.3 stores a private key associated with an X.509 certificate under the web root with insufficient access control, which allows remote attackers to obtain cleartext versions of HTTPS traffic or spoof devices via a direct request to the certificate directory, aka Bug ID CSCuu63501.

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 Cisco TelePresence IX5000 version 8.0.3 stores private keys associated with X.509 certificates under the web root with insufficient access control, allowing remote unauthenticated attackers to download these private keys via direct HTTP requests. Attackers can use the compromised keys to decrypt HTTPS traffic or impersonate the affected devices.

MitigationGenerate new certificate/private key pairs and replace the compromised cryptographic material on affected devices. Configure proper access controls to prevent web-accessible storage of sensitive certificate files and restrict access to the certificate directory.

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 device model
    Determine if the device is a Cisco TelePresence IX5000 series system
    Affected if Device model is Cisco TelePresence IX5000
  2. Check software version
    Access the system administration interface or use CLI command 'show version' to confirm the installed Cisco TelePresence System Software Ix version
    Affected if Version is 8.0.3
  3. Test web-accessible private keys
    Using a web browser or HTTP client, attempt to access typical certificate storage paths under the web root (such as /certs/, /private/, or similar paths containing .key or .pem files) via HTTP without authentication
    Affected if Private key files (X.509 private keys with .key or .pem extension) are downloadable via direct HTTP requests without authentication
  4. Verify HTTPS certificate exposure
    Inspect any downloaded certificates to confirm they contain associated private keys (look for BEGIN PRIVATE KEY or BEGIN RSA PRIVATE KEY markers in downloaded files)
    Affected if Downloaded certificate files contain usable private key material

A system is affected if it is a Cisco TelePresence IX5000 running software version 8.0.3 and private key files associated with X.509 certificates are accessible via direct HTTP requests to the web root.

Mitigation

Generate new certificate/private key pairs and replace the compromised cryptographic material on affected devices. Configure proper access controls to prevent web-accessible storage of sensitive certificate files and restrict access to the certificate directory.
