A vulnerability, which was classified as critical, has been found in Tenda G3 15.11.0.20. This issue affects the function formSetDebugCfg of the file /goform/setDebugCfg. The manipulation of the argument enable/level/module leads to stack-based buffer overflow. The attack may be initiated 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.
