An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as a 'staticGet' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'staticGet <node_name attr>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.
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.
