A stack-based buffer overflow vulnerability in the my_cgi.cgi component of certain D-Link devices, including the DSP-W215 version 1.02, can be exploited via a specially crafted HTTP POST request to the /common/info.cgi endpoint. This flaw enables an unauthenticated attacker to achieve remote code execution with system-level privileges.

→Detect HTTP POST requests targeting the /common/info.cgi endpoint on D-Link DSP-W215 devices, which may indicate exploitation of the stack-based buffer overflow in my_cgi.cgi ↗
→Unauthenticated POST requests to /common/info.cgi should be treated as highly suspicious; no authentication is required to trigger the vulnerability ↗
→A Metasploit module exists for this vulnerability (dlink_dspw215_info_cgi_bof); monitor for exploit framework signatures in HTTP POST bodies to /common/info.cgi ↗

·Exploitation was validated in an emulated environment, not confirmed on physical hardware; detection fidelity on real devices may differ ↗
·The vulnerability affects multiple D-Link device models beyond the DSP-W215 v1.02; scope of affected firmware versions is not fully enumerated in available sources ↗
