Security readout for executives and security teams
Plain-English summary
Schneider Electric U.motion Builder before v1.3.4 has a SQL injection flaw in nfcserver.php. A malicious sessionid value can affect the underlying SQLite query. The sources do not provide severity scoring, exploit impact, or evidence of active exploitation, so urgency should be based on whether the software exists in production or operational technology environments.
Executive priority
Treat this as an inventory-driven operational risk. Prioritize remediation if U.motion Builder is deployed in building automation, operational technology, or other sensitive environments, because SQL injection can threaten application data integrity even when public exploit evidence is not shown.
Technical view
CVE-2018-7773 affects Schneider Electric U.motion Builder Software versions prior to v1.3.4. The vulnerable code path processes nfcserver.php and passes the sessionid input parameter into an SQLite database query in a way that is subject to SQL injection. No CVSS vector, CWE mapping, or detailed vendor mitigation text is included in the provided sources.
Likely exposure
Exposure is limited to environments running Schneider Electric U.motion Builder Software before v1.3.4, especially where nfcserver.php is reachable by untrusted users or networks. The bundle does not identify other Schneider Electric products as affected.
Exploitation context
The provided sources do not show active exploitation, and the CVE bundle marks KEV as false. Public details are limited to the vulnerable component, parameter, affected version range, and SQL injection class.
Researcher notes
Evidence is sparse. The key technical indicators are nfcserver.php, the sessionid parameter, SQLite query handling, and U.motion Builder versions before v1.3.4. Avoid broad Schneider Electric exposure assumptions without confirming product and version.
Mitigation direction
- Identify any U.motion Builder installations and record their exact versions.
- Upgrade affected installations to v1.3.4 or later where supported by Schneider Electric guidance.
- Restrict access to U.motion Builder interfaces from untrusted networks.
- Review Schneider Electric advisory SEVD-2018-095-01 for official remediation details.
Validation and detection
- Confirm no U.motion Builder installation is below v1.3.4.
- Verify whether nfcserver.php is present and reachable in deployed environments.
- Review application and web logs for unusual requests involving nfcserver.php or sessionid.
- Document compensating access controls where immediate upgrade is not possible.
