Security readout for executives and security teams
Plain-English summary
CVE-2018-7764 is a directory traversal flaw in Schneider Electric U.motion Builder before v1.3.4. A vulnerable runscript.php applet mishandles the 's' parameter. The sources do not provide severity scoring or confirmed exploitation, so urgency depends on whether this software is present and reachable.
Executive priority
Treat as a targeted product exposure check, not a confirmed emergency from the supplied evidence. Prioritize inventory and vendor-guided upgrade if U.motion Builder is present, especially in operational or building-management environments.
Technical view
The vulnerability is in the runscript.php applet of Schneider Electric U.motion Builder software versions prior to v1.3.4. Improper processing of the 's' parameter creates a directory traversal condition. The supplied record does not include CVSS, CWE, exploit details, or impact specifics.
Likely exposure
Organizations using Schneider Electric U.motion Builder software before v1.3.4 are the known affected population. Exposure is unclear from the supplied sources and depends on deployment, accessibility of the vulnerable applet, and whether the software remains in use.
Exploitation context
The supplied bundle does not show CISA KEV listing or any cited evidence of active exploitation. No public exploit status is established here. Directory traversal vulnerabilities can expose sensitive files, but the actual impact for this product is not described in the sources.
Researcher notes
Evidence is sparse: the record identifies product, affected range, vulnerable applet, and parameter, but lacks CVSS, CWE, impact, prerequisites, and exploit status. Avoid assuming broader U.Motion product impact beyond U.motion Builder prior to v1.3.4.
Mitigation direction
- Inventory Schneider Electric U.motion Builder installations and record deployed versions.
- Upgrade affected U.motion Builder software to v1.3.4 or later per Schneider guidance.
- Review Schneider advisory SEVD-2018-095-01 for product-specific remediation instructions.
- Limit unnecessary access to systems hosting the software while remediation is pending.
Validation and detection
- Confirm whether U.motion Builder is deployed in the environment.
- Check each installation version against the affected range: prior to v1.3.4.
- Review access paths to any runscript.php applet exposure.
- Verify remediation status against Schneider Electric advisory SEVD-2018-095-01.
