CVE-2018-7774
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 vulnerability exists within processing of localize.php in Schneider Electric U.motion Builder software versions prior to v1.3.4. The underlying SQLite database query is subject to SQL injection on the username input parameter.
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 vulnerability in Schneider Electric U.motion Builder's localize.php script allows remote attackers to inject malicious SQL commands through the username parameter, which is directly concatenated into an SQLite database query without proper input sanitization.

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.
-
Confirm U.motion Builder installationIdentify whether Schneider Electric U.motion Builder software is installed on the system by checking for its installation directories or running software inventory commandsAffected if U.motion Builder is present on the system
-
Check installed versionLocate and read the version information for U.motion Builder (such as in the application metadata, about dialog, or version file), then compare the version number to 1.3.4Affected if The installed version is lower than 1.3.4
-
Locate localize.php scriptFind the localize.php script within the U.motion Builder web application directory structureAffected if The localize.php script exists in the application
-
Verify username parameter handlingExamine the localize.php script source code to confirm that the username parameter is directly concatenated into SQL queries without parameterized queries or input sanitizationAffected if The code shows direct concatenation of the username parameter into SQL queries
-
Check network accessibilityDetermine if the U.motion Builder web interface is exposed to untrusted networks or the internetAffected if The application is accessible from untrusted network segments
The environment is affected if U.motion Builder version is installed and is lower than 1.3.4, and the localize.php script handles user input without proper SQL parameterization.

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 data1.3.4
Upgrade to U.motion Builder v1.3.4 or later which patches the SQL injection vulnerability. If immediate patching is not feasible, implement network segmentation to limit exposure to trusted users only.
