CVE-2023-5515
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 · uneditedThe responses for web queries with certain parameters disclose internal path of resources. This information can be used to learn internal structure of the application and to further plot attacks against web servers and deployed web applications.
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 confidenceThis is an information disclosure vulnerability where web query responses with certain parameters expose internal path information of application resources. An attacker can use this leaked path data to map the application's internal structure and plan further attacks against the web server.

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 Esoms versionLocate the installed Hitachienergy Esoms version number in the system management interface, software inventory, or product documentation. Common locations include the about page, system information panel, or version log files.Affected if The installed version is 6.3.13 or lower.
-
Confirm web interface is enabledVerify that the Esoms web application server is running and accessible by attempting to reach the web interface URL (typically on ports 80, 443, or configured service ports). Check if the web service process is active.Affected if The web interface is accessible and running.
-
Test for path information in web responsesSend legitimate web queries or requests to the Esoms application and inspect the HTTP responses. Look for file system paths, directory structures, or internal resource locations in the returned data, particularly in error messages, debug output, or query results.Affected if HTTP responses contain internal file system paths or directory structures that should not be exposed.
-
Inspect error messages and debug outputTrigger various application functions or intentionally submit invalid input to generate error conditions. Capture and examine the resulting error pages or messages for leaked internal path information.Affected if Error messages or debug output reveal absolute or relative paths to application resources.
-
Review response headers and metadataExamine HTTP response headers, XML responses, or JSON API responses for any path-related information that exposes the internal application structure.Affected if Responses include internal path information in headers, API payloads, or metadata fields.
The environment is affected if Esoms version is 6.3.13 or lower and the web interface exposes internal file system paths in any responses.

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 dataSanitize all web responses to remove or obfuscate internal path information, particularly in error messages and debug output. Implement input validation and ensure path traversal protections are in place.
