CVE-2018-7777: The vulnerability is due to insufficient handling of update_file request parameter on update_module.php in...

Security readout for executives and security teams

Schneider Electric U.motion Builder before v1.3.4 mishandles an update request parameter. An authenticated remote user could send a crafted request to the server. Business urgency depends on whether this building-management software is deployed, reachable, and accounts are exposed. Exposure is most likely where U.motion Builder is installed, accessible over a network, and permits authenticated users beyond tightly controlled administrators. Internet-facing or weakly managed deployments raise concern. The bundle does not identify affected CPEs or default exposure. Prioritize remediation if U.motion Builder is used in operational building environments or reachable outside a trusted admin network. Authentication lowers the bar from unauthenticated internet risk, but command-injection characterization makes exposed legacy deployments important to fix. Mitigation focus: Inventory Schneider Electric U.motion Builder deployments and versions.; Upgrade affected software to v1.3.4 or follow Schneider Electric advisory guidance.; Restrict access to trusted administrative networks only..
