A vulnerability was found in Tenda O1 1.0.0.7(10648) and classified as critical. Affected by this issue is the function fromDhcpSetSer of the file /goform/DhcpSetSer. The manipulation of the argument dhcpStartIp/dhcpEndIp/dhcpGw/dhcpMask/dhcpLeaseTime/dhcpDns1/dhcpDns2 leads to stack-based buffer overflow. The attack may be launched 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.
