Security readout for executives and security teams
Plain-English summary
CVE-2018-7776 is an information disclosure issue in Schneider Electric U.motion Builder. Versions before 1.3.4 can return system information through error.php, exposing sensitive details to an attacker. The bundle does not provide a CVSS score or evidence of active exploitation.
Executive priority
Prioritize remediation where U.motion Builder is deployed in operational environments or reachable beyond trusted administration networks. Business urgency is moderate in practice but severity is formally unknown from the supplied sources.
Technical view
The vulnerability is in error.php in Schneider Electric U.motion Builder software prior to v1.3.4. The disclosed behavior is unintended return of system information containing sensitive data. Public bundle details do not include CWE, prerequisites, authentication context, or a detailed trigger condition.
Likely exposure
Exposure is limited to environments running Schneider Electric U.motion Builder software before v1.3.4. Risk is higher if the Builder interface or related web components are reachable from untrusted networks.
Exploitation context
The source bundle does not list CISA KEV status and provides no cited evidence of active exploitation. It only supports that an attacker may receive sensitive system information from the vulnerable component.
Researcher notes
Evidence is sparse: no CVSS, CWE, exploit status, authentication requirement, or detailed advisory text is included in the bundle. Treat this as source-grounded information disclosure and avoid assuming broader impact such as code execution.
Mitigation direction
- Upgrade U.motion Builder to v1.3.4 or later, per Schneider Electric guidance.
- Review Schneider Electric advisory SEVD-2018-095-01 for vendor remediation details.
- Restrict access to U.motion Builder interfaces to trusted administrative networks.
- Avoid exposing Builder web components directly to the internet.
Validation and detection
- Inventory Schneider Electric U.motion Builder installations and record installed versions.
- Confirm no deployed instance is running a version prior to v1.3.4.
- Review application logs for unexpected access to error.php.
- Verify network controls restrict Builder access to authorized administrators.
