Multiple stack-based buffer overflows in TP-Link WR940N WiFi routers with hardware version 4 allow remote authenticated users to execute arbitrary code via the (1) ping_addr parameter to PingIframeRpm.htm or (2) dnsserver2 parameter to WanStaticIpV6CfgRpm.htm.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
