The manipulation of the argument dhcpStartIp/dhcpEndIp/dhcpGw/dhcpMask/dhcpLeaseTime/dhcpDns1/dhcpDns2 leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-262142 is the identifier assigned to this vulnerability.
