| Title | Remote OS command Injection at setDiagnosisCfg on TOTOLink EX1200L |
|---|
| Description | ## Description and impact
Function `setDiagnosisCfg` executes os command `ping`. An attacker can execute remote os command using crafted payload at `Ping Address`
## Root-cause
When the function `setDiagnosisCfg` is called, it crafts the ping command following syntax `ping %s -w %d &>/var/log/pingCheck`
The value of `Ping Address` is not validated, therefore an attacker can send a craftted payload to execute OS command and get the command output with `getDiagnosisCfg`
