| タイトル | Totolink A3300R 17.0.0cu.557_b20221024 Command Injection |
|---|
| 説明 | The vulnerability exists within the router's shttpdservice. It allows a remote attacker to execute arbitrary operating system commands by sending a specially crafted network request. The technical root cause involves unsafe handling of user input in a function chain:
A user-supplied parameter named "ip" is read by the program.
This parameter's value is passed to the Uci_Set_Strfunction.
Subsequently, the value of "ip" is unsafely concatenated into a command string (variable v11) using snprintf.
This crafted command string is then passed to and executed by the CsteSystemfunction via the execv()system call. |
