CVE-2024-25660
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 · uneditedThe 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 confidenceThe 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Nokia TNMS versionCheck the installed version of Nokia Transcend Network Management System on the system and confirm it is exactly 19.10.3Affected if The installed version is 19.10.3
-
Confirm WebDAV service is enabledIdentify whether the WebDAV service component is running or enabled on the TNMS installationAffected if WebDAV service is active and accessible on the system
-
Inspect WebDAV service account privilegesExamine 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 accountAffected if The WebDAV service runs with elevated privileges (administrator, system, or similar high-privilege account)
-
Check for unauthorized file access capabilityFrom 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 directoryAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedRestrict 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.
