CVE-2016-0864
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 · uneditedTollgrade SmartGrid LightHouse Sensor Management System (SMS) Software EMS before 5.1, and 4.1.0 Build 16, allows remote attackers to obtain sensitive report and username information via unspecified vectors.
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 · moderate confidenceTollgrade SmartGrid LightHouse SMS Software contains an information disclosure vulnerability in versions prior to 5.1 (and 4.1.0 Build 16) that allows unauthenticated remote attackers to obtain sensitive report data and usernames via unspecified network vectors. The CVSS 5.3 score indicates a network-exploitable, low-complexity attack requiring no authentication.

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.
-
Identify installed Tollgrade SmartGrid LightHouse SMS versionLocate the software version information through the product management console, about page, or system configuration files. Common locations include the administration interface or system information panel within the Lighthouse application.Affected if The installed version is 5.0 or earlier, or is version 4.1.0 (any build). Versions 5.1 and later are not affected.
-
Determine if management interface is network-accessibleReview network configuration to check whether the Lighthouse SMS management interface (typically ports used for web-based or API access) is exposed to untrusted networks. Check firewall rules and access control lists.Affected if The management interface is reachable from untrusted networks without authentication restrictions, as the vulnerability allows unauthenticated access.
-
Review access logs for unauthorized data access attemptsExamine Lighthouse SMS server logs for requests that may indicate probing for sensitive report data or user information. Look for unusual query patterns or data export activities.Affected if Logs show unauthorized requests for report data or user information from external IP addresses.
-
Audit stored report data for unauthorized accessInspect recently accessed or exported reports within the system to determine if any sensitive data was accessed without proper authentication credentials.Affected if Report data shows evidence of access or export without corresponding authenticated user sessions in the audit logs.
Your environment is affected if the installed Tollgrade SmartGrid LightHouse SMS version is 5.0 or earlier, or is version 4.1.0, and the management interface is network-accessible to unauthenticated attackers.

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 dataUpgrade Tollgrade SmartGrid LightHouse SMS to version 5.1 or later to address the vulnerability. If immediate upgrade is not feasible, restrict network access to the EMS management interfaces and implement monitoring for unauthorized access attempts.
