Dir 878
Monthly
Stack-based buffer overflow in the D-Link DIR-878 wireless router (firmware 120B05) lets an attacker corrupt the stack through the SetWan3Settings handler of the WAN Settings component by supplying an oversized Primary/Secondary argument (typically DNS/gateway fields). Successful exploitation can crash the device or achieve arbitrary code execution on the router. Reported by VulDB; a third-party technical advisory is published on GitHub, but there is no public exploit identified at time of analysis and it is not in CISA KEV.
