CVE-2021-29295 1 Dlink 2 Dsp-w215, Dsp-w215 Firmware 2021-08-17 5.0 MEDIUM 7.5 HIGH
** UNSUPPORTED WHEN ASSIGNED **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.
CVE-2021-29296 1 Dlink 2 Dir-825, Dir-825 Firmware 2021-08-17 5.0 MEDIUM 7.5 HIGH
