CVE-2018-7785
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 · uneditedIn Schneider Electric U.motion Builder software versions prior to v1.3.4, a remote command injection allows authentication bypass.
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 remote command injection vulnerability exists in Schneider Electric U.motion Builder software versions prior to v1.3.4. The vulnerability allows attackers to inject operating system commands, which can be leveraged to bypass authentication mechanisms. This critical flaw affects building automation systems and could allow unauthenticated remote attackers to gain full system 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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed U.motion Builder versionLocate the U.motion Builder installation and check the software version information, typically available in the application itself, its About dialog, or installed program listingAffected if The version displayed is lower than 1.3.4
-
Verify web service availabilityDetermine if the U.motion Builder web interface or associated HTTP service is accessible on the networkAffected if The web service is exposed and the installed version is below 1.3.4
-
Check for unauthorized access indicatorsReview system logs, authentication logs, and web server access logs for unusual commands, unexpected authentication bypass events, or suspicious shell command patternsAffected if Logs show command injection attempts or evidence of unauthorized command execution
-
Assess network exposureDetermine if the U.motion Builder service is directly accessible from untrusted networks or the internetAffected if The service is internet-facing and runs a vulnerable version
A user is affected if Schneider Electric U.motion Builder version 1.3.4 or later is NOT installed and the service is network-accessible.

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 · scoped1.3.4
Upgrade Schneider Electric U.motion Builder to version 1.3.4 or later to remediate this vulnerability. Organizations should also restrict network access to U.motion systems and monitor for indicators of compromise.
v1.3.4
- Identify the current installed version of U.motion Builder software
- Confirm the installed version is prior to v1.3.4
- Obtain the U.motion Builder v1.3.4 or later from the official Schneider Electric source
- Follow Schneider Electric's standard upgrade procedure for U.motion Builder
- After upgrade, verify the installation is running v1.3.4 or later
- Test that the application functions normally post-upgrade
