SQL injection vulnerability in the CheckLogin function in includes/functions.php in Limny 1.01, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the username parameter.

Multiple cross-site request forgery (CSRF) vulnerabilities in Limny 2.0 allow remote attackers to (1) hijack the authentication of users or administrators for requests that change the email address or password via the user action to index.php, and (2) hijack the authentication of the administrator for requests that create a new user via the admin/modules/user/new action to limny/index.php.
