A vulnerability, which was classified as critical, has been found in TP-Link VN020 F3v(T) TT_V6.2.1021. Affected by this issue is some unknown functionality of the component DHCP DISCOVER Packet Parser. The manipulation of the argument hostname leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
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.
The product writes data past the end, or before the beginning, of the intended buffer.
