CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-50665 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 46th 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.
CVE-2025-50665 is a buffer overflow vulnerability (CWE-120) in the D-Link DI-8003 device running firmware version 16.07.26A1. The flaw stems from improper handling of input parameters in the /web_keyword.asp endpoint, specifically the name, en, time, mem_gb2312, and mem_utf8 parameters processed in HTTP GET requests.
An unauthenticated attacker with network access can exploit this vulnerability by sending a specially crafted HTTP GET request to the affected endpoint. According to the CVSS v3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), exploitation requires low complexity, no privileges or user interaction, and results in high availability impact, enabling a denial-of-service condition such as device crash or reboot.
D-Link has issued security advisory SAP10505 detailing the issue, accessible at https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10505, alongside a general security bulletin page at https://www.dlink.com/en/security-bulletin/. Additional documentation appears in vulnerability collections like https://github.com/xiaotea/iot-vulnerability-collection/blob/main/README.md.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and analysis can find missing size checks before deployment.
Input validation directly enforces size checks before buffer copies.
Engineering principles require bounds checking and safe buffer handling in design.
Memory protection limits the impact of an overflow once it occurs.

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.
