An attacker can supply a crafted input that overflows the buffer and causes the device to crash, resulting in a loss of availability. The weakness is a classic buffer copy without bounds checking (CWE-120).", "risk_and_exploitability": "The CVSS score of 7.5 indicates a high risk to availability. The EPSS score is less than 1\u00a0percent, suggesting low current exploitation likelihood. The vulnerability is not listed in the CISA KEV catalog, so there is no evidence of widespread active exploitation. Access appears to be remote through the device\u2019s web interface, so an attacker only needs network connectivity to the target device. Because the flaw is a buffer overflow, a remote attacker could trigger the crash without authentication if the function is exposed publicly."}}}}, "created": "2026-04-08T19:33:45.538680+00:00", "title": "Buffer Overflow leading to Denial of Service in D-Link DI-8300 Firmware", "updated": "2026-04-13T14:26:11.731650+00:00", "vendors": ["dlink", "dlink$PRODUCT$di-8300"]}
