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
Loftware Spectrum through 4.6 has unprotected JMX Registry.

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

Loftware Spectrum through version 4.6 exposes a Java Management Extensions (JMX) registry without authentication or authorization controls. This allows unauthenticated remote attackers to access the JMX interface, potentially enabling remote code execution through the deployment of malicious MBeans or abuse of JMX management operations.

MitigationImmediately restrict network access to the JMX registry via firewall rules or disable remote JMX access if not required. If JMX remote access is necessary, enable JMX authentication with strong credentials and configure SSL/TLS encryption.

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 Loftware Spectrum installation
    Look for Loftware Spectrum installation directories (commonly in C:\Program Files\Loftware Spectrum or /opt/loftware/spectrum on Linux), or check for the spectrum service running via 'sc query' on Windows or 'ps aux | grep spectrum' on Linux.
    Affected if Loftware Spectrum is installed and running on the system.
  2. Determine Loftware Spectrum version
    Check the version by examining the spectrum_version file in the installation directory, or look at the service properties. Compare the installed version against the affected range (4.6 and below).
    Affected if The installed version is 4.6 or lower.
  3. Identify running JMX processes
    On Windows, run 'netstat -ano | findstr LISTENING' to find ports typically used by JMX (such as 9010, 9011, or custom ports). On Linux, use 'netstat -tlnp' or 'ss -tlnp'. Look for Java processes listening on these ports.
    Affected if JMX-related ports are open and listening.
  4. Check JMX configuration for authentication
    Locate the startup scripts (spectrum.bat, spectrum.sh, or wrapper.conf) and examine Java system properties for -Dcom.sun.management.jmxremote.authenticate=false or similar settings. Also check for the absence of -Dcom.sun.management.jmxremote.password.file configuration.
    Affected if JMX authentication is disabled (jmxremote.authenticate=false) or no password file is configured.
  5. Verify JMX network exposure
    Check if the JMX service is bound to all interfaces (0.0.0.0) rather than localhost only. Inspect the com.sun.management.jmxremote.host property or the binding address in netstat output. Ensure the JMX port is not accessible from external network sources.
    Affected if JMX is bound to 0.0.0.0 or an external IP address and is accessible from the network without authentication.

If Loftware Spectrum version 4.6 or lower is running with JMX ports exposed to the network and authentication is disabled, the environment is affected by this CVE.

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.

From vendor data
Upgrade available Upgrade to a release after 4.6
Interim mitigation

Immediately restrict network access to the JMX registry via firewall rules or disable remote JMX access if not required. If JMX remote access is necessary, enable JMX authentication with strong credentials and configure SSL/TLS encryption.
