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
Atos Unify OpenScape 4000 Platform V10 R1 before Hotfix V10 R1.42.2 4000 and Manager Platform V10 R1 before Hotfix V10 R1.42.2 allow command injection by an authenticated attacker into the platform operating system, leading to administrative access, via dtb pages of the platform portal. This is also known as OSFOURK-23719.

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 4000 Platform V10 R1 before Hotfix V10 R1.42.2 contains a command injection vulnerability in the dtb pages of the platform portal. An authenticated attacker can inject arbitrary operating system commands through these web interface parameters, leading to administrative access and full compromise of the underlying platform operating system.

MitigationApply vendor Hotfix V10 R1.42.2 or later to the OpenScape 4000 Platform and Manager Platform. If immediate patching is not possible, restrict network access to the management portal to trusted IP addresses and monitor for unauthorized administrative access.

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 OpenScape 4000 product version
    Access the platform management interface and navigate to the system information or about section to determine if the version is 10.x (specifically V10 R1). Look for build or hotfix information.
    Affected if The installed version is OpenScape 4000 Assistant or Manager version 10 without Hotfix V10 R1.42.2 applied.
  2. Verify Hotfix V10 R1.42.2 installation
    Check the system's installed patches, hotfixes, or build information within the platform portal or system administration console. Look specifically for hotfix version V10 R1.42.2.
    Affected if Hotfix V10 R1.42.2 is NOT installed or the installed hotfix version is lower than V10 R1.42.2.
  3. Confirm web portal accessibility
    Determine if the platform portal (web management interface) is accessible on the network. Check if dtb pages are reachable via HTTP/HTTPS.
    Affected if The web management portal is exposed and accessible (authenticated command injection requires access to these dtb pages).
  4. Review portal authentication status
    Check if the platform portal is configured with authentication and identify any legitimate administrative accounts. Look for unexpected or unauthorized accounts.
    Affected if The portal uses weak, default, or compromised credentials that could allow authenticated access to an attacker.

You are affected if OpenScape 4000 Assistant or Manager version 10 is running without Hotfix V10 R1.42.2 and the web portal is network-accessible with valid credentials.

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

Apply vendor Hotfix V10 R1.42.2 or later to the OpenScape 4000 Platform and Manager Platform. If immediate patching is not possible, restrict network access to the management portal to trusted IP addresses and monitor for unauthorized administrative access.

Recommended fix High confidence

Hotfix V10 R1.42.2

  1. Identify the current version of Unify Openscape 4000 (Assistant or Manager) V10 R1 installed in the environment
