| 标题 | Totolink A3300R 17.0.0cu.557_b20221024 Command Injection |
|---|
| 描述 |
The vulnerability resides 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 is a command injection flaw in the handling of user input:
The attack vector is a user-supplied parameter named enable.
The program flow reads this parameter in the sub_41458Cfunction and passes it to Uci_Set_Str.
Subsequently, the value of the "enable" parameter is unsafely concatenated into a command string (variable v11) using snprintf.
This crafted command string is then passed to the CsteSystemfunction, where it is ultimately executed by the execv()system call, leading to arbitrary command execution. |
