VAR-201909-1438

Vulnerability from variot - Updated: 2024-11-23 22:33

An issue was discovered in D-Link DIR-806 devices. There is a stack-based buffer overflow in function hnap_main at /htdocs/cgibin. The function will call sprintf without checking the length of strings in parameters given by HTTP header and can be controlled by users. And it finally leads to a stack-based buffer overflow via a special HTTP header. D-link DIR-806 The device contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Dlink DIR-806 is a wireless AC1200 dual-band router. An attacker could exploit this vulnerability to run Shellcode via a long HTTP header that starts with "SOAPAction: http://purenetworks.com/HNAP1/GetDeviceSettings/"
