CVE-2016-8280
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 · uneditedDirectory traversal vulnerability in Huawei eSight before V300R003C20SPC005 allows remote authenticated users to read arbitrary files 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 confidenceDirectory traversal vulnerability in Huawei eSight allows authenticated remote users to read arbitrary files on the server by manipulating file path references, enabling exposure of sensitive system files.

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 if Huawei eSight is installedCheck for eSight installation directory (commonly at C:\Huawei\eSight or /opt/eSight) or look for eSight processes in running servicesAffected if eSight software is present on the system
-
Determine installed eSight versionCheck the version file in the eSight installation directory, typically found in the 'version' or 'version.ini' file, or use the eSight client to view system informationAffected if Installed version matches v300r002c00, v300r003c10, or v300r003c20
-
Verify if eSight management interface is accessibleCheck if the eSight web console port (typically 8080 or 443) is listening and accessible from networkAffected if Management interface is exposed on network and accepts authentication
-
Review eSight access logs for directory traversal patternsExamine web server logs in the eSight installation directory (logs folder) for suspicious URL patterns containing '../' or multiple forward slashes in file path parametersAffected if Logs show requests with traversal sequences like '..' or unusual file path parameters to unknown endpoints
-
Check for unauthorized access to system filesReview eSight audit logs for successful file retrieval operations, especially accessing files outside the expected upload/download directoriesAffected if Logs indicate retrieval of system files (e.g., /etc/passwd, Windows system files) that were not initiated by legitimate administrators
Environment is affected if Huawei eSight v300r002c00, v300r003c10, or v300r003c20 is installed with its management interface accessible to network users, regardless of whether authentication is required for the traversal attempt.

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 Huawei eSight to version V300R003C20SPC005 or later. Until upgrade is possible, limit access to the eSight management interface to trusted authenticated users only.
