CVE-2025-50657 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Dlink Di-8003 Firmware. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 directly prevents buffer overflows by enforcing validation of the pid parameter in the /trace.asp endpoint to reject malformed inputs.
SI-2 ensures timely patching of the buffer overflow flaw in D-Link DI-8003 firmware version 16.07.26A1 as advised in D-Link security bulletins.
SI-16 mitigates memory corruption from the buffer overflow via safeguards like address space layout randomization or non-executable memory.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in unauthenticated public web endpoint (/trace.asp) directly enables remote exploitation of a network device (T1190) to trigger application/system DoS via memory corruption (T1499.004).
NVD Description
A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper handling of the pid parameter in the /trace.asp endpoint.
Deeper analysisAI
CVE-2025-50657 is a buffer overflow vulnerability classified under CWE-121 in the D-Link DI-8003 device running firmware version 16.07.26A1. The flaw stems from improper handling of the pid parameter in the /trace.asp endpoint, which can lead to memory corruption when processing malformed input.
The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating it is exploitable over the network with low attack complexity, no authentication or user interaction required, and unchanged impact scope. Unauthenticated remote attackers can trigger the buffer overflow to cause a denial-of-service condition, resulting in high availability impact such as device crashes or reboots, with no direct confidentiality or integrity effects.
D-Link has published security advisories addressing this issue, including support announcement SAP10505 at https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10505 and the company's security bulletin page at https://www.dlink.com/en/security-bulletin/.
