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
An issue was discovered in Infinera hiT 7300 5.60.50. Cleartext storage of sensitive password in firmware update packages allows attackers to access various appliance services via hardcoded credentials.

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 Infinera hiT 7300 optical networking device firmware version 5.60.50 stores sensitive passwords in cleartext within firmware update packages. These hardcoded credentials embedded in the firmware allow attackers to authenticate to various appliance services without needing to discover or crack the credentials.

MitigationReplace all hardcoded credentials in the firmware with dynamic, securely-stored credentials or external authentication mechanisms; revoke compromised credentials and rotate to new secure credentials; implement firmware integrity validation to detect tampering.

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
    Check the device identification or system information to confirm the device is an Infinera or Nokia hiT 7300 optical networking device. This may be accessible via device management interface, CLI, or device label.
    Affected if Device is not an Infinera or Nokia hiT 7300 unit, then this specific CVE does not apply.
  2. Check installed firmware version
    Access the device firmware version through the management interface, CLI command, or system status page. Look for a version field showing the currently running firmware.
    Affected if Firmware version is exactly 5.60.50 - only this specific version is affected by this CVE.
  3. Obtain firmware update package
    If firmware upgrade packages are available (downloads, update files, or stored archives), retrieve the firmware package file for the version in question.
    Affected if Firmware packages are not accessible for inspection, but the combination of device model and version 5.60.50 indicates potential exposure.
  4. Inspect firmware package contents for cleartext passwords
    Examine the firmware package file (if accessible) for embedded plaintext credentials. Look for password strings, credential files, or configuration files within the firmware archive that contain unhashed or unencrypted passwords.
    Affected if Cleartext passwords are found embedded within the firmware package - this confirms the vulnerability is present.

Device must be a Nokia hiT 7300 running firmware version 5.60.50 AND its firmware update packages contain cleartext credentials for the environment to be affected by this CVE.
