VAR-202504-3391
Vulnerability from variot - Updated: 2025-05-17 23:07A vulnerability, which was classified as critical, has been found in Netgear EX6120 1.0.3.94. Affected by this issue is the function sub_30394. The manipulation of the argument host leads to buffer overflow. The attack may be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way. of netgear EX6120 The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. NETGEAR EX6120 is a wireless extender from NETGEAR. The vulnerability is caused by the sub_30394 function parameter host failing to correctly verify the length of the input data. Attackers can use this vulnerability to execute arbitrary code on the system or cause a denial of service
