A flaw has been found in Linksys E1700 1.0.0.4.003. Affected by this vulnerability is the function setWan of the file /goform/setWan. This manipulation of the argument DeviceName/lanIp causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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.
