4Description
A vulnerability has been found in Belkin F9K1122 1.00.33 and classified as critical. Affected by this vulnerability is the function formSetWanStatic of the file /goform/formSetWanStatic of the component webs. The manipulation of the argument m_wan_ipaddr/m_wan_netmask/m_wan_gateway/m_wan_staticdns1/m_wan_staticdns2 is directly passed by the attacker/so we can control the m_wan_ipaddr/m_wan_netmask/m_wan_gateway/m_wan_staticdns1/m_wan_staticdns2 leads to os command injection. The attack can be launched 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.
