D-link DIR-816 A2_v1.10CNB04.img is vulnerable to Buffer Overflow via /goform/form2Wan.cgi. When wantype is 3, l2tp_usrname will be decrypted by base64, and the result will be stored in v94, which does not check the size of l2tp_usrname, resulting in stack overflow.
Add your gear to cvedb and we'll alert you only when dlink ships something exploited.
