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
PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an insufficient authentication issue. The camera does not properly enforce authentication to /cgi-bin/param.cgi when requests are sent without an HTTP Authorization header. The result is a remote and unauthenticated attacker can leak sensitive data such as usernames, password hashes, and configurations details. Additionally, the attacker can update individual configuration values or overwrite the whole file.

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 PTZOptics PT30X-SDI/NDI-xx camera firmware before 6.3.40 contains an authentication bypass vulnerability in /cgi-bin/param.cgi. When HTTP requests to this endpoint omit the Authorization header, the camera fails to enforce authentication, allowing any remote attacker to read sensitive configuration data including usernames and password hashes, modify individual configuration parameters, or completely overwrite the configuration file.

MitigationUpdate all affected PTZOptics PT30X-SDI/NDI-xx cameras to firmware version 6.3.40 or later. If immediate patching is not feasible, isolate these devices behind a firewall or within a restricted VLAN to limit exposure to untrusted networks.

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 model is PT30X-SDI or PT30X-NDI-xx
    Access the camera web interface or check the device label/metadata to identify the exact model number. Look for 'PT30X-SDI' or 'PT30X NDI' in the product identifier.
    Affected if The device model is PT30X-SDI or any PT30X-NDI-xx variant (such as PT30X-NDI-G2).
  2. Check the installed firmware version
    Log into the camera web interface and navigate to the System Settings or About page to view the firmware version. Alternatively, send an HTTP GET request to the device and examine any version information in the response headers or HTML.
    Affected if The firmware version is lower than 6.3.40 (for example, 6.3.38, 6.3.0, etc.).
  3. Test the /cgi-bin/param.cgi endpoint for unauthenticated access
    Send an HTTP request to http://<camera-ip>/cgi-bin/param.cgi without including any Authorization header or authentication cookies. Examine the response for sensitive content.
    Affected if The endpoint returns a valid response with usernames, password hashes, or configuration data rather than requiring authentication (HTTP 401 or redirect to login).
  4. Verify sensitive configuration is exposed
    Inspect the response from the unauthenticated /cgi-bin/param.cgi request. Look for parameters that reveal admin usernames, password hash values, or system configuration settings.
    Affected if The response contains plaintext usernames, password hash strings (such as in parameters like 'username' or 'password' or 'pwd'), or exposes writable configuration parameters.

Your environment is affected if you have a PTZOptics PT30X-SDI or PT30X-NDI-xx camera running firmware below version 6.3.40, and the /cgi-bin/param.cgi endpoint responds to requests without an Authorization header.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 6.3.40 or later
Fixed in 6.3.40
Interim mitigation

Update all affected PTZOptics PT30X-SDI/NDI-xx cameras to firmware version 6.3.40 or later. If immediate patching is not feasible, isolate these devices behind a firewall or within a restricted VLAN to limit exposure to untrusted networks.

Recommended fix High confidence

Firmware 6.3.40

  1. Obtain firmware version 6.3.40 or later from the official PTZOptics support website or vendor
  2. Access the PT30X camera's administrative web interface
  3. Navigate to the firmware update or system settings section
  4. Upload and apply the firmware version 6.3.40 or later
  5. Reboot the camera as prompted by the update process
  6. Verify the firmware version has been updated to 6.3.40 or later
  7. Confirm that /cgi-bin/param.cgi now requires authentication by testing without an Authorization header
