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
The WebDAV service in Infinera TNMS (Transcend Network Management System) 19.10.3 allows a low-privileged remote attacker to conduct unauthorized file operations, because of execution with unnecessary privileges.

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

The WebDAV service in Infinera TNMS 19.10.3 runs with elevated privileges, allowing a low-privileged remote attacker to perform unauthorized file system operations. This privilege escalation occurs because the service executes with more system rights than necessary for its function.

MitigationRestrict WebDAV service privileges to the minimum required for its intended function, or implement proper access controls to prevent low-privileged users from performing file operations outside their authorized scope.

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 Nokia TNMS version
    Check the installed version of Nokia Transcend Network Management System on the system and confirm it is exactly 19.10.3
    Affected if The installed version is 19.10.3
  2. Confirm WebDAV service is enabled
    Identify whether the WebDAV service component is running or enabled on the TNMS installation
    Affected if WebDAV service is active and accessible on the system
  3. Inspect WebDAV service account privileges
    Examine the user account or service context under which the WebDAV service executes - verify if it runs with administrative or elevated system rights rather than a restricted service account
    Affected if The WebDAV service runs with elevated privileges (administrator, system, or similar high-privilege account)
  4. Check for unauthorized file access capability
    From a low-privilege remote perspective, test whether the WebDAV endpoint permits file system operations outside the intended scope - such as accessing files outside the designated WebDAV share directory
    Affected if Low-privileged users can perform file operations beyond their authorized scope via WebDAV

A user is affected if they have Nokia TNMS version 19.10.3 with the WebDAV service enabled and that service is running with elevated privileges, allowing unauthorized file system access by low-privileged accounts.

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

Restrict WebDAV service privileges to the minimum required for its intended function, or implement proper access controls to prevent low-privileged users from performing file operations outside their authorized scope.

Recommended fix Moderate confidence

Contact Infinera for the specific fixed release (version higher than 19.10.3)

  1. Contact Infinera support to obtain the fixed version of TNMS that addresses CVE-2024-25660
  2. Schedule a maintenance window for the upgrade
  3. Back up the current TNMS configuration and any critical data
  4. Apply the vendor-provided upgrade following Infinera's official upgrade documentation
  5. Verify the WebDAV service is functioning correctly after upgrade
  6. Confirm the fix resolves the privilege escalation issue by testing with low-privileged accounts
  7. Monitor for any abnormal behavior post-upgrade
Caveat Review Infinera release notes for any configuration or compatibility changes between 19.10.3 and the fixed version
