Mall23 contains a flaw that may allow a remote attacker to carry out an SQL injection attack. The issue is due to the 'infopage.asp' script not properly sanitizing user-supplied input to the 'idPage' variable. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 4.09 or higher, as it has been reported to fix this vulnerability. In addition, Mall23 has released a patch (via the auto-update feature) for some older versions.
