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
A Directory Traversal issue was discovered in SpiderControl SCADA Web Server. An attacker may be able to use a simple GET request to perform a directory traversal into system files.

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 in SpiderControl SCADA Web Server allows remote attackers to use crafted GET requests with path traversal sequences (e.g., ../../../) to access files outside the web root directory, potentially exposing sensitive system files, configuration data, or credentials.

MitigationImplement strict input validation on all file path parameters using allow-lists, normalize paths before processing, and configure the web server to restrict file access to intended directories only.

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 if SpiderControl SCADA Web Server is installed
    Check for SpiderControl web server processes running on the system (common ports: 80, 443, 8080, 8443) or look for installation directories containing 'SpiderControl' in the program files. On Windows, check the Services list for SpiderControl services. On Linux, check for spidermw or similar daemon processes.
    Affected if SpiderControl SCADA Web Server is installed and running on the system
  2. Verify web server is network accessible
    Use a browser or curl command to access the web server HTTP interface. For example: curl -v http://TARGET_IP:PORT/ where PORT is the web server port (commonly 80 or 8080).
    Affected if The SpiderControl web interface is reachable over the network (even on localhost)
  3. Test for directory traversal vulnerability
    Send a crafted GET request with path traversal sequences to attempt to access files outside the web root. For example: curl -v http://TARGET_IP:PORT/../../../windows/win.ini or curl -v http://TARGET_IP:PORT/../../../etc/passwd (adjust path depth as needed).
    Affected if The server returns content from files outside the intended web root directory, indicating successful directory traversal
  4. Check for exposure to untrusted networks
    Review firewall rules and network configuration to determine if the SpiderControl web server HTTP/HTTPS ports are accessible from untrusted networks or the internet rather than only from trusted internal networks.
    Affected if The web server port is open to untrusted networks or the internet without proper access controls
  5. Review access logs for exploitation attempts
    Examine SpiderControl web server access logs for requests containing '../' sequences, path traversal patterns, or attempts to access system files like win.ini, passwd, or config files.
    Affected if Historical or current logs show directory traversal attempts against the web server

If SpiderControl SCADA Web Server is installed and its web interface is accessible, the environment is affected since all versions contain the directory traversal vulnerability.
