Summary

The D-Link DIR-3040 router is susceptible to a stack-based buffer overflow vulnerability due to inadequate validation of user-supplied strings within the prog.cgi binary. This flaw specifically impacts the handling of HNAP requests directed to the lighttpd webserver operating on TCP ports 80 and 443. Exploitation of this vulnerability enables an adjacent attacker to execute arbitrary code with root-level privileges, provided they have authenticated access. This situation underscores the importance of rigorous validation checks in network device software to mitigate potential threats.
