A vulnerability, which was classified as critical, was found in Tenda i21 1.0.0.14(4656). This affects the function formQosManageDouble_auto. The manipulation of the argument ssidIndex leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The identifier VDB-262137 was assigned to this vulnerability. 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.
