Exploiting Integer Based SQL Injection In Nested SQL Queries
https://blog.gdssecurity.com/labs/2013/10/8/exploiting-integer-based-sql-injection-in-nested-sql-queries.html

basically what it says is, if you change enableAS values and post it to "this.LCDispatcher?nav=hp" you get different results...

meaning, you can get access to all of your results this way...
