Overview

• CVE Identifier: CVE-2025-10034
• Affected Device: D-Link DIR-825, firmware version 1.08.01 and earlier — these units are no longer supported by D-Link NVDCvetodo.
• Vulnerability Type: Buffer overflow in the get_ping6_app_stat function of the ping6_response.cg file within the embedded httpd component. Manipulating the ping6_ipaddr argument enables unauthenticated, remote execution NVDCvetodoOpenCVE.
• Severity:
  • CVSS v3.1: 8.8 (High) OpenCVECvetodo
  • CVSS v4.0: 8.7 (High) OpenCVENVD
  • Public exploit availability and unsupported status further elevate the risk Cvetodovuldb.com.
• Exploitability: Low complexity, no user interaction needed. The vulnerable process handles web interface requests, making this vulnerability easy to exploit remotely CvetodoFeedly.

Risk Summary

Impact Area	Description
Confidentiality	High — data exposure or device compromise possible
Integrity	High — attacker can modify device configuration
Availability	High — device could crash or go offline
Device Status	End of support — no vendor patches available

Recommended Actions (Mitigation Strategies)

Since the DIR-825 is unsupported and patching is not currently available, here’s how to protect your network:

1. Disable Remote Management
   Immediately turn off remote web interface access on the affected device CvetodoFeedly.
2. Restrict Local Access
   Limit management access to trusted IP addresses only and enforce network segmentation to isolate the device.
3. Deploy Network-Level Protections
   Use firewall rules to block incoming traffic on HTTP/HTTPS ports. Monitor for anomaly traffic to the device CvetodoFeedly.
4. Upgrade or Replace Device
   The most effective long-term strategy is replacing the DIR-825 with a currently supported, secure router.
5. Continuous Monitoring
   Add the device to your SIEM or IDS systems to detect exploitation attempts.
