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 · unedited
Directory traversal vulnerability in the web application in Symmetricom s350i 2.70.15 allows remote attackers to read arbitrary files via a (1) ../ (dot dot slash) or (2) ..\ (dot dot forward slash) before a file name.

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 · high confidence

A directory traversal vulnerability exists in the web application of Symmetricom s350i version 2.70.15. Remote attackers can read arbitrary files on the system by using path traversal sequences (../ or ..\) in file requests to the web interface.

MitigationImplement strict input validation on the web server to reject path traversal sequences, restrict web server file system permissions to prevent access outside intended directories, and apply vendor-supplied firmware updates when available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify S350i device on the network
    Locate devices running the S350i web application by scanning for HTTP/HTTPS services or reviewing network inventory. The web interface typically listens on ports 80 or 443.
    Affected if The device is a Microsemi or Symmetricom S350i time server with an accessible web interface.
  2. Check the firmware version
    Log into the web interface and navigate to the status or system information page, or query the device via SNMP or CLI command 'show system' to retrieve the firmware version.
    Affected if The firmware version is exactly 2.70.15.
  3. Verify the web server is enabled
    Confirm the HTTP/HTTPS service is running on the device by attempting to access the login page or checking the service status via CLI (e.g., 'show web-server' or similar command).
    Affected if The web server service is active and accepting HTTP/HTTPS connections.
  4. Test for path traversal vulnerability
    Send an HTTP GET request to the web interface using a path traversal sequence, such as: GET /../../../../etc/passwd HTTP/1.1 or similar pattern targeting known file paths. Compare the response to expected behavior.
    Affected if The web server returns content from files outside the intended web root directory.

You are affected if you have a Microsemi S350i device running firmware version 2.70.15 with the web interface enabled, and the device responds to path traversal requests by returning arbitrary file contents.
