No other product versions or variants are confirmed to be affected, but the issue may exist in other firmware releases that share the same code path.", "description_and_impact": "A buffer overflow occurs in the http_lanport parameter that is processed by the /webgl.asp endpoint on the D-Link DI-8003 device. The vulnerability arises from improper handling of input data, leading to a memory overwrite that could allow a malicious actor to execute arbitrary code. The impact is severe as it permits attackers to gain full control of the device and, if the device is a critical network gateway, to compromise the network it serves.", "risk_and_exploitability": "No CVSS or EPSS metrics are provided, yet a buffer overflow indicates a high severity potential for exploitation. An attacker would need access to the router\u2019s web interface, either from the local network or via a publicly exposed management console. The absence of a public exploit or patch does not reduce the inherent risk associated with memory corruption, so the vulnerability remains a critical threat if the device is exposed to untrusted traffic."}}}}, "created": "2026-04-08T19:45:01.994314+00:00", "title": "Buffer Overflow in D\u2011Link DI\u20118003 via http_lanport Parameter", "updated": "2026-04-08T19:45:01.994348+00:00", "vendors": [], "weaknesses": ["CWE-119"]}
