D-Link DIR 645A1 1.06B01Beta01 was discovered to contain a stack overflow via the service= variable in the genacgimain function.

D-Link DIR-645 1.03 A1 is vulnerable to Buffer Overflow. The hnapmain function in the cgibin handler uses sprintf to format the soapaction header onto the stack and has no limit on the size.

Stack-based buffer overflow in the DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary code via a long string in a GetDeviceSettings action to the HNAP interface.
