An issue was discovered in MK-AUTH 19.01. There are SQL injection issues in mkt/ PHP scripts, as demonstrated by arp.php, dhcp.php, hotspot.php, ip.php, pgaviso.php, pgcorte.php, pppoe.php, queues.php, and wifi.php.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
