Null Pointer Dereference vulnerability exists in D-Link DSP-W215 1.10, which could let a remote malicious user cause a denial of servie via usr/bin/lighttpd. It could be triggered by sending an HTTP request without URL in the start line directly to the device. NOTE: The DSP-W215 and all hardware revisions is considered End of Life and as such this issue will not be patched

D-Link DSP-W215 1.26b03 devices allow information disclosure by intercepting messages on the local network, as demonstrated by a Squid Proxy.

D-Link DSP-W215 1.26b03 devices send an obfuscated hash that can be retrieved and understood by a network sniffer.

Stack-based buffer overflow in the do_hnap function in www/my_cgi.cgi in D-Link DSP-W215 (Rev. A1) with firmware 1.01b06 and earlier, DIR-505 with firmware before 1.08b10, and DIR-505L with firmware 1.01 and earlier allows remote attackers to execute arbitrary code via a long Content-Length header in a GetDeviceSettings action in an HNAP request.
