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 Common Management Portal V10 before V10 R4.17.0 and V10 R5.1.0 allows an authenticated attacker to execute arbitrary code on the operating system via a Common Management Portal web interface Path traversal vulnerability allowing write access outside the intended folders. This is also known as OCMP-6592.

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 Common Management Portal versions prior to V10 R4.17.0 and V10 R5.1.0 contains a path traversal vulnerability in the web interface that allows authenticated attackers to write files outside the intended folder boundaries, leading to arbitrary operating system code execution.

MitigationUpgrade the OpenScape Common Management Portal to V10 R4.17.0, V10 R5.1.0, or later to remediate the path traversal vulnerability.

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 the installed OpenScape Common Management Portal version
    Access the web management interface and navigate to the About or System Information section, or check the product documentation for version display commands. Compare the displayed version number against the affected ranges (prior to V10 R4.17.0 or V10 R5.1.0).
    Affected if The installed version is 10.x prior to R4.17.0 or prior to R5.1.0
  2. Verify the web management interface is accessible
    Attempt to reach the OpenScape Common Management Portal web interface via its configured HTTP/HTTPS URL (commonly port 443 or 8443). Confirm the service responds.
    Affected if The web interface is exposed and reachable on the network
  3. Confirm authentication is enabled for the portal
    Check the web interface login page status. The vulnerability requires an authenticated attacker, so determine whether local or remote authentication (LDAP/AD) is configured and active.
    Affected if Authentication is configured and functional, allowing attacker to obtain valid credentials
  4. Review file upload or write capabilities in the web interface
    Log into the portal and navigate to sections that handle file uploads, backups, certificates, or configuration imports. These are typical paths where the path traversal file write may be exploitable.
    Affected if The portal includes file upload or write features accessible to authenticated users

You are affected if the installed OpenScape Common Management Portal version is 10.x prior to R4.17.0 or prior to R5.1.0 and the web management interface with authentication is enabled.

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

Upgrade the OpenScape Common Management Portal to V10 R4.17.0, V10 R5.1.0, or later to remediate the path traversal vulnerability.

Recommended fix High confidence

V10 R4.17.0 or V10 R5.1.0

  1. 1. Identify the current installed version of Unify Openscape Common Management Portal V10
  2. 2. Determine which release track (R4 or R5) is currently in use
  3. 3. Download the appropriate fixed version: V10 R4.17.0 (for R4 track) or V10 R5.1.0 (for R5 track) from the official Atos Unify support portal
  4. 4. Follow the standard upgrade procedure documented in the Openscape Common Management installation guide
  5. 5. After upgrade, verify the Common Management Portal is accessible and functioning normally
  6. 6. Confirm the path traversal vulnerability is remediated by reviewing release notes for OCMP-6592
Caveat Standard upgrade risks apply - review backup procedures and compatibility with other Openscape components before upgrading
