CVE-2017-7974
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 · uneditedA path traversal information disclosure vulnerability exists in Schneider Electric's U.motion Builder software versions 1.2.1 and prior in which an unauthenticated user can execute arbitrary code and exfiltrate files.
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 confidenceA path traversal vulnerability in Schneider Electric U.motion Builder software versions 1.2.1 and prior allows unauthenticated attackers to manipulate file paths to execute arbitrary code and exfiltrate sensitive files from the server by escaping intended directory boundaries.

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.
-
Identify U.motion Builder installationSearch for U.motion Builder installation directories or check system inventory/software list for Schneider Electric U.motion BuilderAffected if The software is installed on the system
-
Determine installed versionCheck the installed version of U.motion Builder (typically found in the software itself, about section, or installation metadata) and compare to <= 1.2.1Affected if The installed version is 1.2.1 or any prior version
-
Verify web management interface exposureCheck if the U.motion Builder web interface is accessible on the network (typically ports 80/443 or custom ports used by the application)Affected if The management interface is exposed to network access
-
Inspect access logs for path traversalReview web server or application logs for requests containing path traversal patterns such as ../, ..\, or absolute path referencesAffected if Logs show path traversal attempts or suspicious file access patterns
If U.motion Builder version 1.2.1 or prior is installed and its web interface is network-accessible, the environment is vulnerable to CVE-2017-7974 path traversal attacks.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpgrade U.motion Builder to a patched version beyond 1.2.1; if patching is delayed, restrict network access to the management interface and deploy WAF rules to block path traversal patterns (../, ..\, absolute path references).
