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
Zoom Call Recording 6.3.1 from Eleveo is vulnerable to Java Deserialization attacks targeting the inbuilt RMI service. A remote unauthenticated attacker can exploit this vulnerability by sending crafted RMI requests to execute arbitrary code on the target host.

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

Eleveo Zoom Call Recording 6.3.1 contains a Java deserialization vulnerability in its built-in RMI (Remote Method Invocation) service. An unauthenticated remote attacker can exploit this by sending specially crafted RMI requests to achieve arbitrary code execution on the targeted system.

MitigationApply any available vendor patches for Zoom Call Recording, or if RMI is not required, disable the RMI service and restrict network access to the application. Consider network segmentation to limit exposure of the affected service.

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. Verify Eleveo Call Recording version
    Locate the Eleveo Zoom Call Recording installation and check its version information. Common methods include: reviewing installation directories for version files, checking the application's about/help dialog, or querying the software via its administrative interface if available.
    Affected if The installed version is exactly 6.3.1 (no other versions are listed as affected in this CVE).
  2. Confirm RMI service is enabled
    Identify whether the built-in RMI (Remote Method Invocation) service is active. This may be checkable through the application's service configuration, process list showing Java RMI-related ports (typically 1099 by default), or administrative console settings.
    Affected if The RMI service is running or enabled; the vulnerability only applies when this service is active.
  3. Assess network accessibility of RMI port
    Determine if the RMI service port is exposed to the network. Use network scanning tools or review firewall rules to check if the RMI port (commonly port 1099) is reachable from untrusted networks or the internet.
    Affected if The RMI port is accessible from external or untrusted networks, enabling unauthenticated attackers to send crafted requests.

A system is affected if it runs Eleveo Zoom Call Recording version 6.3.1 with the RMI service enabled and network-accessible to untrusted users.
