CVE-2018-7841
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 SQL Injection (CWE-89) vulnerability exists in U.motion Builder software version 1.3.4 which could cause unwanted code execution when an improper set of characters is entered.
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 confidenceSQL Injection (CWE-89) in U.motion Builder v1.3.4 allows unauthenticated remote attackers to inject malicious SQL queries via unsanitized input fields, potentially achieving code execution on the underlying database server.

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.
-
Locate U.motion Builder installationSearch the system for U.motion Builder software or check program directories for the application. Common paths may include C:\Program Files\Schneider Electric\ or /opt/umotion/ directories on Linux systems.Affected if U.motion Builder software is found on the system
-
Identify installed versionRight-click the U.motion Builder application executable, select Properties, and view the Version tab, or use the software's About/Help menu to display the version information.Affected if The installed version is exactly 1.3.4
-
Determine if web interface is exposedCheck if U.motion Builder's web server component is running and accessible by accessing the application's web interface on typical ports such as 80, 443, or 8080.Affected if The web interface is accessible and accepting user input
-
Review application logs for SQL injection indicatorsExamine U.motion Builder log files for suspicious database error messages, malformed SQL syntax, or unusual database queries that may indicate exploitation attempts.Affected if Logs contain SQL error messages or suspicious query patterns
The system is affected if U.motion Builder version 1.3.4 is installed and its web interface with user input fields is 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.
From vendor dataImplement parameterized queries or prepared statements for all database interactions, apply strict input validation and output encoding, and upgrade to a patched version if available.
