Multiple SQL injection vulnerabilities in modules/forum/post.php in RunCMS 2M1 allow remote authenticated users to execute arbitrary SQL commands via (1) the pid parameter, which is not properly handled by the store function in modules/forum/class/class.forumposts.php, or (2) the topic_id parameter.

Static code injection vulnerability in RunCMS 2M1 allows remote authenticated administrators to execute arbitrary PHP code via the "Filter/Banning" feature, as demonstrated by modifying modules/system/cache/bademails.php using the "Prohibited: Emails" action, and other unspecified filters.

Multiple SQL injection vulnerabilities in RunCMS 2M1 allow remote authenticated users to execute arbitrary SQL commands via the (1) forum parameter to modules/forum/post.php and possibly (2) forum_id variable to modules/forum/class/class.permissions.php.

RunCMS 2M1, when running with certain error_reporting levels, allows remote attackers to obtain sensitive information via (1) the op[] parameter to modules/contact/index.php or (2) uid[] parameter to userinfo.php, which leaks the installation path in an error message when these parameters are used in a call to the preg_match function.
