How to fix CVE-2025-50652?

Within 24 hours: Identify all D-Link DI-8003 routers in your environment and verify current firmware version (check for 16.07.26A1). Within 7 days: Contact D-Link support to determine firmware availability status and timeline; restrict administrative interface access (/saveparm_usb.asp) to trusted administrative networks only via firewall rules. Within 30 days: Apply any released firmware updates when available; if no patch is released, implement network segmentation to isolate affected devices from untrusted network segments.

Is D-Link affected by CVE-2025-50652?

D-Link DI-8003 routers running firmware 16.07.26A1 are vulnerable to unauthenticated denial-of-service attacks through a network-accessible administrative interface, potentially disrupting network availability for affected organizations.

Description

An issue in D-Link DI-8003 16.07.26A1 related to improper handling of the id parameter in the /saveparm_usb.asp endpoint.

Analysis

Buffer overflow in D-Link DI-8003 router firmware 16.07.26A1 enables unauthenticated remote attackers to trigger denial-of-service conditions through malformed id parameter input to /saveparm_usb.asp endpoint. Exploitation requires network access to administrative interface without authentication. CWE-120 classification indicates classic buffer overflow allowing memory corruption. CVSS vector confirms network-exploitable, unauthenticated attack path with high availability impact but no data confidentiality or integrity compromise. No public exploit identified at time of analysis.

Technical Context

CWE-120 buffer overflow stems from insufficient input validation on id parameter at /saveparm_usb.asp. Unbounded memory copy operation allows oversized inputs to corrupt stack/heap memory structures, crashing routing processes. CVSS complexity rating (AC:L) indicates trivial exploitation requiring only HTTP parameter manipulation without timing or race conditions.

Affected Products

D-Link DI-8003 industrial router firmware version 16.07.26A1. Vendor D-Link. Specific CPE unavailable; impacts confirmed single firmware build on DI-8003 hardware platform.

Remediation

No vendor-released patch identified at time of analysis. D-Link security bulletin (https://www.dlink.com/en/security-bulletin/) should be monitored for firmware updates addressing CVE-2025-50652. Immediate mitigations: restrict administrative interface access to trusted management networks using firewall rules, disable external WAN-side access to web management ports (typically TCP 80/443), implement network segmentation isolating DI-8003 devices from untrusted networks. If device supports it, disable USB configuration functionality at /saveparm_usb.asp if not operationally required. Organizations unable to implement network controls should consider device replacement with patched alternative until D-Link releases firmware fix. Validate vendor advisory for product end-of-life status impacting patch availability.
