Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-13304 is a buffer overflow vulnerability (CWE-119, CWE-120) discovered in D-Link routers, specifically models DWR-M920, DWR-M921, DWR-M960, DWR-M961, and DIR-825M running firmware versions 1.01.07 or 1.1.47. The flaw affects unknown code in the /boafrm/formPingDiagnosticRun file and is triggered by manipulating the 'host' argument.

The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating it can be exploited remotely with low complexity by an attacker possessing low privileges, without requiring user interaction. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially resulting in remote code execution or system crashes.
