A vulnerability classified as critical has been found in Tenda O6 1.0.0.7(2054). Affected is the function fromVirtualSet of the file /goform/setPortForward. The manipulation of the argument ip/localPort/publicPort/app leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
