The vulnerability arises when the /time_group.asp endpoint processes the name and mem parameters without proper bounds checking, leading to an out\u2011of\u2011bounds write (CWE\u2011120). An attacker who can reach this endpoint can send crafted input that overflows the buffer and potentially execute arbitrary code on the device, compromising confidentiality, integrity and availability.", "risk_and_exploitability": "The vulnerability carries a CVSS v3 score of 7.5, indicating high severity. Its EPSS is below 1\u202f% and it is not present in CISA\u2019s KEV catalog, suggesting that large\u2011scale exploitation has not yet been observed. Exploitation would require network access to the router\u2019s internal management interface, likely through a local or remote connection to the device. While discovery of the flaw is straightforward, the low exploit probability combined with the potential for complete device compromise warrants urgent attention."}}}}, "created": "2026-04-08T20:12:56.708813+00:00", "title": "Buffer Overflow in D-Link DI-8003 Web Interface", "updated": "2026-04-14T16:40:33.560242+00:00", "vendors": ["dlink", "dlink$PRODUCT$di-8003"]}
