CVE-2017-14435: An exploitable denial of service vulnerability exists in the web server functionality of Moxa EDR-810 V4.1...

An exploitable denial of service vulnerability exists in the web server functionality of Moxa EDR-810 V4.1 build 17030317. A specially crafted HTTP URI can cause a null pointer dereference resulting in denial of service. An attacker can send a GET request to "/MOXA\_CFG.ini" without a cookie header to trigger this vulnerability.

Security readout for executives and security teams

Plain-English summary

CVE-2017-14435 can crash the web server function on a listed Moxa EDR-810 firmware build. It affects availability, not data theft or tampering. The business risk is outage of devices exposing this management web service, especially if reachable from untrusted networks.

Executive priority

Treat as high priority for exposed operational devices because unauthenticated network traffic can cause service disruption. Prioritize isolation and firmware verification before broader remediation planning.

Technical view

Talos describes a null pointer dereference in Moxa EDR-810 V4.1 build 17030317 web server handling. A specially crafted unauthenticated HTTP request can trigger denial of service. CVSS 3.0 is 7.5: network reachable, low complexity, no privileges, no user interaction, high availability impact.

Likely exposure

Exposure is most likely where Moxa EDR-810 V4.1 build 17030317 devices have the web management service reachable over production, corporate, or internet-facing networks.

Exploitation context

The source bundle states unauthenticated network exploitation is possible. CISA KEV is false in the provided data, and no cited source in the bundle confirms active exploitation.

Researcher notes

The provided evidence supports availability-only impact through a null pointer dereference in the web server path. No CWE is listed, no KEV listing is present, and the bundle does not name a confirmed fixed version.

Mitigation direction

  • Inventory Moxa EDR-810 devices and identify firmware build 17030317.
  • Restrict web management access to trusted administrative networks only.
  • Use VPN, allowlists, or firewall rules for device management interfaces.
  • Check Moxa or Talos guidance for supported firmware updates or vendor fixes.
  • Monitor affected devices for web service crashes or unexpected restarts.

Validation and detection

  • Confirm whether any deployed device matches Moxa EDR-810 V4.1 build 17030317.
  • Verify the web management interface is not reachable from untrusted networks.
  • Review web logs for requests targeting configuration INI resources without normal session context.
  • Confirm compensating controls block unauthenticated access to the management web server.
  • Document any fixed firmware version only after vendor guidance confirms it.
