VAR-202508-2103

Vulnerability from variot - Updated: 2025-09-07 23:08

A vulnerability was determined in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function DHCPReserveAddGroup of the file /goform/DHCPReserveAddGroup. This manipulation of the argument enable_group/name_group/ip_group/mac_group causes stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way. Linksys of RE6250 Firmware and other products from multiple vendors contain buffer error vulnerabilities and stack-based buffer overflow vulnerabilities.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state

This affects the function DHCPReserveAddGroup of the file /goform/DHCPReserveAddGroup. This manipulation of the argument enable_group/name_group/ip_group/mac_group causes stack-based buffer overflow.
