Summary

The D-Link DIR-3040 router is affected by a stack-based buffer overflow vulnerability in the prog.cgi binary. This flaw arises from insufficient validation of user-supplied input, which is copied into a fixed-size buffer within the context of the lighttpd web server running on TCP ports 80 and 443. Network-adjacent attackers can exploit this vulnerability to execute arbitrary code with root privileges, given that they have valid authentication. The issue emphasizes the importance of input validation in preventing unauthorized access and code execution in network devices.
