A vulnerability was found in Linksys E1700 1.0.0.4.003. This affects the function QoSSetup of the file /goform/QoSSetup. Performing manipulation of the argument ack_policy results in stack-based buffer overflow. The attack may be initiated remotely. The exploit has been made public and could 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.
