TitleTOTOLINK NR1800X NR1800X_Firmware V9.1.0u.6279_B20210910 Buffer Overflow
DescriptionIn the NR1800X_Firmware V9.1.0u.6279_B20210910 has a buffer overflow vulnerability in the `setWizardCfg` function. The `v49` variable receives the `ssid` parameter from a POST request. However, since the user can control the input of `ssid`, the statement `urldecode` can cause a buffer overflow vulnerability.
