A vulnerability was determined in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. Affected is the function ipv6cmd of the file /goform/setIpv6. The manipulation of the argument Ipv6PriDns/Ipv6SecDns/Ipv6StaticGateway/LanIpv6Addr/LanPrefixLen/pppoeUser/pppoePass/pppoeIdleTime/pppoeRedialPeriod/Ipv6in4_PrefixLen/LocalIpv6/RemoteIpv4/LanIPv6_Prefix/LanPrefixLen/ipv6to4Relay/ipv6rdRelay/tunrd_PrefixLen/wan_UseLinkLocal/Ipv6StaticIp/Ipv6PrefixLen leads to os command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
