CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-50650 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Dlink Di-8003 Firmware. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A buffer overflow vulnerability, tracked as CVE-2025-50650 and published on 2026-04-08, affects the D-Link DI-8003 router running firmware version 16.07.26A1. The issue stems from inadequate validation of input size in the routes_static parameter processed by the /router.asp endpoint, corresponding to CWE-120. It has a CVSS v3.1 base score of 7.5, rated as high severity due to its potential for remote denial-of-service impact.
An unauthenticated attacker with network access can exploit this vulnerability with low complexity and no user interaction required. By sending a specially crafted HTTP request to the /router.asp endpoint with an oversized routes_static parameter, the attacker triggers a buffer overflow, resulting in high availability impact such as device crashes or reboots, while confidentiality and integrity remain unaffected.
D-Link has published mitigation guidance in security advisories, including SAP10505 at https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10505 and the general security bulletin page at https://www.dlink.com/en/security-bulletin/. Additional details appear in the IoT vulnerability collection at https://github.com/xiaotea/iot-vulnerability-collection/blob/main/README.md. Security practitioners should consult these for patching instructions or workarounds specific to the affected firmware.

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.
Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.
Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.
Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.
Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
