| 标题 | Tenda RX9 Router RX9 Pro Firmware V22.03.02.10、RX9 Pro Firmware V22.03.02.20 Stack-based Buffer Overflow |
|---|
| 描述 | In Tenda RX9 Pro Firmware V22.03.02.20 firmware has a stack overflow vulnerability in the sub_42EA38 function. The var variable receives the list parameter from a POST request. However, since the user can control the input of list, the statement if ( sscanf((int)Var, "%[^,],%[^,],%[^,],%s", v19, v18, v17, v16) == 4 ) can cause a buffer overflow. The user-provided list can exceed the capacity of the v16~v19 arrays, triggering this security vulnerability. |
