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 Atos Unify OpenScape Voice Trace Manager V8 before V8 R0.9.11. It allows authenticated command injection via ftp.

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

Atos Unify OpenScape Voice Trace Manager V8 before V8 R0.9.11 contains an authenticated command injection vulnerability in its FTP functionality. An attacker with valid credentials can inject arbitrary OS commands through FTP operations, potentially achieving remote code execution on the underlying system.

MitigationUpgrade to V8 R0.9.11 or later. Until patched, enforce strict network access controls to limit who can reach the Trace Manager interface and implement monitoring for suspicious FTP activity.

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 installed Trace Manager version
    Access the OpenScape Voice Trace Manager web interface or check system inventory/registry for the exact version number of the Unify Openscape Voice Trace Manager software
    Affected if The installed version is exactly 8.0 (no patches applied)
  2. Confirm FTP service is enabled
    Locate the FTP server configuration within the Trace Manager administrative panel or check if the FTP service process is running on the system
    Affected if FTP functionality is active and accessible on the Trace Manager
  3. Verify network accessibility of Trace Manager
    Check if the Trace Manager web interface and FTP ports are reachable from network locations - typical ports include 80/443 for web and 21 for FTP
    Affected if The Trace Manager interface is exposed beyond trusted networks without proper access controls
  4. Review FTP operation logs
    Examine Trace Manager logs for recent FTP operations, particularly look for unusual or unexpected FTP commands or authentication events
    Affected if There are FTP log entries containing unexpected command patterns or operations from unfamiliar users

You are affected if the installed OpenScape Voice Trace Manager is exactly version 8.0, FTP is enabled, and the system is accessible (even with valid credentials required for exploitation)

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to V8 R0.9.11 or later. Until patched, enforce strict network access controls to limit who can reach the Trace Manager interface and implement monitoring for suspicious FTP activity.

Recommended fix High confidence

V8 R0.9.11 or later

  1. 1. Identify the current version of OpenScape Voice Trace Manager V8 installed in your environment
  2. 2. Obtain the fixed version V8 R0.9.11 or later from the official Atos Unify distribution channels or support portal
  3. 3. Plan and schedule a maintenance window for the upgrade
  4. 4. Before upgrading, ensure you have a complete backup of the current configuration and data
  5. 5. Apply the upgrade to OpenScape Voice Trace Manager from your current version to V8 R0.9.11 or later
  6. 6. After upgrade, verify the application starts successfully and all services are running
  7. 7. Validate that the FTP functionality is working correctly post-upgrade
  8. 8. Review audit logs to confirm no unauthorized command injection attempts occurred
